If a non-sinusoidal voltage is present, type selection should be basedon multiplying the peak voltage by a factor of 0.707.3.The voltage measured at 1 mA meets the requirements of “paragraph 4.3 of CECC specification 42000” .The tolerance on the voltage at 1 mA is ± 10%.4.High energy surges are generally of longer duration. The maximum energy for one pulse of 10 × 1000 µs is given as a reference for longerduration pulses. This pulse can be characterised by peak current (I p ) and pulse width t 2 (virtual time of half I p value, following “IEC 60060-2, section 6” ). If V p is the clamping voltage corresponding to I p , the energy absorbed in the varistor is determined by the formula:where:a)K is dependent on the value of t 2 when the value of t 1 is between 8 µs and 10 µs; see Peak Current as a Function of Pulse Width drawing.5. A current wave of 8 × 20 µs (requirement of “paragraph B.2.10.1 of CECC specification 42000” ) is used as a standard for pulse current andclamping voltage ratings. The maximum non-repetitive transient current is given for one pulse applied during the life of the component.E K V p ×I p ×t 2×=元器件交易网2322 59. .....Varistors Vishay BCcomponents ELECTRICAL CHARACTERISTICSDERATING CURVE PEAK CURRENT AS A FUNCTION OFPULSE WIDTH元器件交易网2322 59. .....Vishay BCcomponents VaristorsNote1.Outline of the Ø20 mm differs from the other dimensions.DIMENSIONS in millimetersFor dimensions, see ComponentDimensions and catalog Numbers table.Ø20 mm only.Outline of component with straight leads.Outline of component with kinked leads.For dimensions, see ComponentDimensions and catalog Numbers table.Outline of component with flanged leads.For dimensions, see ComponentDimensions and catalog Numbers table.Outline of flanged leads.元器件交易网2322 59. .....

Forthis reason the usual graphs of R = f(T) are replaced byResistance Values at Intermediate Temperatures Tables,together with a formula to calculate the characteristics with ahigh precision.FORMULAE TO DETERMINE NOMINALRESISTANCE VALUESThe resistance values at intermediate temperatures, or theoperating temperature values, can be calculated using thefollowing interpolation laws(extended “Steinhart and Hart”):(1)(2)where:A, B, C, D, A1, B1, C1 and D1 are constant valuesdepending on the material concerned; see table below.R ref is the resistance value at a reference temperature (inthis event 25 °C).T is the temperature in K.Formulae numbered (1) and (2) are interchangeable with anerror of max. 0.005 °C in the range 25 °C to 125 °C andmax. 0.015 °C in the range−40 °C to +25 °C.DETERMINATION OF THERESISTANCE/TEMPERATURE DEVIATIONFROM NOMINAL VALUEThe total resistance deviation is obtained by combining the‘R25-tolerance’ and the ‘resistance deviation due toB-tolerance’.When:X = R25-toleranceY = resistance deviation due to B-toleranceZ = complete resistance deviation,then: or Z ≈ X + Y.When:TC = temperature coefficient∆T = temperature deviation,then:The temperature tolerances are plotted in the graphs on theprevious page.Example: at 0 °C, assume X = 5%, Y = 0.89% andTC = 5.08%/K (see T able ), then:A NTC with a R25-value of 10 kΩ has a value of 32.56 kΩbetween −1.17 and +1.17 °C.R (T)R=ref e×A B T⁄C T2⁄D T3⁄+++()T (R) = A1B1RR ref---------ln C1ln2RR ref---------D1ln3RR ref---------+++⎝⎠⎛⎞1–Z1X100---------+⎝⎠⎛⎞1Y100---------+⎝⎠⎛⎞1–×= 100×%∆T ZTC-------=Z15100---------+10.89100-----------+1–×⎩⎭⎨⎬⎧⎫100%×=1.05 1.0089 1–×{} 100% 5.9345% 5.93%≈()=×˙=∆T ZTC-------5.935.08----------- 1.167 °C 1.17≈°C)(===Notes1.Temperature < 25 °C.2.Temperature ≥25 °C.2322 640 3/4/6....Vishay BCcomponentsNTC Thermistors, Accuracy Line For technical questions contact: nlr.europe@Document Number: 290492322 640 3/4/6....NTC Thermistors, Accuracy Line Vishay BCcomponents Document Number: 29049For technical questions contact: nlr.europe@ 5 2.0128 2.16−3.7120.1310 1.6767 1.59−3.6016.7715 1.4042 1.04−3.5014.0420 1.18210.51−3.3911.8225 1.00000.00−3.3010.00300.85000.50−3.208.50350.72590.98−3.117.26400.6226 1.44−3.03 6.23450.5363 1.89−2.94 5.36500.4639 2.33−2.86 4.64550.4029 2.75−2.78 4.03600.3512 3.16−2.71 3.51650.3073 3.56−2.64 3.07700.2698 3.95−2.57 2.70750.2377 4.32−2.50 2.38800.2101 4.69−2.43 2.10850.1864 5.04−2.37 1.86900.1658 5.38−2.31 1.66950.1479 5.72−2.25 1.481000.1323 6.05−2.20 1.321050.1187 6.36−2.14 1.191100.1068 6.67−2.09 1.071150.0964 6.98−2.040.961200.08717.27−1.990.871250.07907.56−1.940.791300.07177.84−1.900.721350.06538.11−1.850.651400.05968.37−1.810.601450.05458.63−1.770.551500.05008.89−1.730.50T oper(°C)R T/R25∆R DUE TOB-TOLERANCE(%)TC(%/K)R25(Ω)2322 640 .....;

The Vishay BCcomponents range of Positive Temperature Coefficient (PTC) thermistors includes devices specially designed to provide overcurrent protection.Typical telephone line showing where PTC thermistors can be used for overcurrent protection.1.MDF: Main Distribution Frame; C.O.: Central Office Switching; T.E.: Subscriber Terminal Equipment; S.B.: Set-top Box.2.UL 1434 approved types.元器件交易网2322 66. 9....Vishay BCcomponentsPTC Thermistors, Overload ProtectionFor TelecommunicationDIMENSIONSin millimeters COMPONENT OUTLINEFor dimensions see Specific Physical Dimentions and Packaging table.Lead pitch F = 5 mm +0.6/-0.1.Lead thickness d = 0.6 mm ±10%.OVERCURRENT PROTECTION OF TELECOMMUNICATION LINESThe PTC thermistor must protect the telephone line circuit against overcurrent which may be caused by the following examples:• Surges due to lightning strikes on or near to the line plant. • Short-term induction of alternating voltages from adjacent power lines or railway systems, usually caused when these lines or systems develop faults.• Direct contact between telephone lines and power lines.To provide good protection under such conditions a PTC thermistor is connected in series with each line, usually as secondary protection; see Typical Telephone Line drawing on page 1. H owever, even with primary line protection (usually a gas discharge tube), the PTC thermistor must fulfil severe requirements.Surge pulses of up to 2 kV can occur and in order to withstand short-term power induction the PTC thermistor must withstand high voltages. If the line has primary protection a 220 V to 300 V PTC thermistor is adequate.Without primary protection, however, a 600 V PTC device is necessary. Vishay BCcomponents manufacturers a range of PTC thermistors (see Electrical Data and Ordering Information Table ) covering both requirements.In the case of direct contact between the telephone line and a power line, the PTC thermistor must withstand very highinrush power at normal mains voltage. Under such conditions, overload currents of up to 10 A on a 230 V mains could occur for up to several hours. To handle this power, the resistance/temperature characteristic of the thermistor must have a very steep slope and the ceramic must be extremely homogeneous.In case of overcurrent due to short-term induction of alternating voltages, currents of several AMPs with voltages as high as 650 V RMS can be present for several seconds For standard high voltage applications, resistance values from 25 to 50 Ω are available. H owever, ISDN networks which carry high-frequency sound and vision, need lower line impedance.Telecommunication designers are therefore demanding high voltage thermistors with much lower R 25 values, which places even greater demands on the manufacture of PTC thermistors. For these applications PTC thermistors which have a R 25 value of 10 Ω with voltages in the 300 to 600 V RMS range are available.In a typical telephone line application, two PTC thermistors are used, one each for the tip and ring (or A and B) wire together with their series resistors. For good line balance it is important that the thermistor and resistor pairs are matched.On request, Vishay BCcomponents can supply matched or binned PTC thermistors with R 25 values matched to as close as 0.5 Ω .元器件交易网2322 66. 9....PTC Thermistors, Overload ProtectionFor TelecommunicationVishay BCcomponentsNotes1.Taped in accordance with “IEC 60286-2”; standard packaging: 1500 units/reel.2.Naked disc ceramic for substrate mounting, available on request.3.Insulated version is also available.7.0 4.0 2.5 ±0.5−10.0taped H0 = 16 mm661 931218.5 4.0 2.5 ±0.5 4.1 ±0.511.5bulk661 931248.5 4.0 2.5 ±0.5−11.5taped H0 = 16 mm661 931468.5 4.0 2.5 ±0.5 4.1 ±0.511.5bulk661 931358.0 5.0 2.5 ±0.5−11.0taped H0 = 16 mm661 930568.5 4.0 2.0 ±0.5−11.0taped H0 = 16 mm661 9313910.5 5.0 2.0 ±0.5−12.6taped H0 = 16 mm662 9312913 5.5 4.0 ±1.020 min.18.0bulk662 9311413 5.5 4.0 ±1.020 min.18.0bulk662 93131DMAX.TMAX.H2L1H3MAX.PACKAGING(1)(2)CATALOGNUMBER2322 ... .....PACKAGINGAll tape and reel specifications are in accordance with “IEC 60286-3”.

A block diagram of this circuit is shown in Figure1.Modulation Control / Modulator / Input StageThe modulator is capable of driving modulation currents up to 75mA. There are two modes for adjusting the modulation current:Mode 1: The modulation current is adjusted by an external resistor (R MOD). The IC has an internal temperature compensation circuit for compensating the temperature characteristic of laser diode slope efficiency. With the external resistor (R TC) the modulation current temperature coefficient is adjustable. The temperature input itself is derived from chip junction temperature.Mode 2: The modulation current is controlled by using a low frequency pilot signal. The controller cutoff frequency is adjustable by external capacitor (C MOD). Mode 2 is suitable for data rates 1.25Gbit/s (depending on laser diode).There is an option for using data input latch.Input Signal MonitorAn input signal monitor circuit delivers a logic signal HWA and an internal signal which is used for laser disabling if data input is constantly high or low.Bias Control / Bias GeneratorThe bias controller controls the LD optical output power by adjusting the bias current. The controller cutoff frequency is adjustable by external capacitor (C BIAS). A min. cutoff frequency is integrated. The laser bias current will start at < 500µA after laser enable. Laser Supervisor / V CC SupervisorThe laser supervisor circuit monitors the laser output power by the means of monitor diode feedback. The voltage generated by monitor diode circuit is compared to a reference. If the input voltage deviates more than ±2dB (optical power ±1dB) from this reference the laser diode is switched off and a fault indication is generated. The V CC supervisor monitors the circuit power supply and switches off the laser if the V CC level is below the reset threshold. It is keeping the laser output down for the adjusted delay time (power on delay) after V CC has risen above the V CC reset threshold.Figure1General Circuit Block Diagram –Number of pins: 42–IC available as die2Electrical Characteristics2.1Absolute Maximum RatingsAbsolute Maximum Ratings which may not be exceeded to the device without causing permanent damage or degradation.

The maximum supply current is defined for driving the upper limits of bias current and modulation current with worst case junction temperature and with a V CC of 5.5V (V CC =V CCA =V CCD ).4)This describes the AC modulation current (the DC component is the overall offset current). AC modulation current is drawn by O at V D > V DN , it is drawn by ON at V D < V DN . I OH refers to drawn modulation current (AC +DC). I OL refers to an inactive current output (DC current only).5)See Table 2 for operating conditions junction temperature.6)Inactive current output (see also 4)).7)Modulation current when the laser diode is disabled.8)Valid for V CC =V CCA =V CCD =5V. It is possible to increase the output voltage range for the V CC range of 5V ±0.5V of about 0.85V by using the Pad V CCD2 instead of V CCD (see Figure 14). The specified limits for data and clock inputs are valid for V CCD .9)Adjustment of programmable parameter by resistor value within this range (see Chapter 2.4).10)Adjusting the modulation current by R MOD notice that the decreasing of R MOD will increase the modulation current. R MOD in combination with R TC has to be adjusted that the modulation current is smaller than 50mA or 75mA respectively over specified temperature range. If R MOD -Pad is not connected (open input) there will be no modulation current at the output O/ON.11)Modulation current adaptation within junction temperature range. Low junction temperature represents a low additional modulation current. High junction temperature represents a high additional modulation current. If R TC -Pad is not connected there will be no noteworthy modulation current adaptation.12)Data/clock inputs are internally connected to V BBD /V BBC by resistor R 1/R 2 with a differential termination by R IN .See data input stage description (see Figure 9).13)The resistance is guaranteed for junction temperature 25°C.Table 3Characteristics and Operating Conditions (cont ’d)SP ParameterSym-bolLimit ValuesUnit Condi-tionmin.typ.max.14)If data input duty cycle falls below lower limit or exceeds upper limit the laser will be disabled by ISM circuit.On the other hand, the laser will be enabled whenever the data input duty cycle goes back to the allowed range.Data input duty cycle refers to the quotient given by number of ones divided by number of zeros within serial data stream. The ISM-circuit evaluates the mean value of the duty cycle (integrator). The cutoff frequency of ISM f ISM is defined for data pattern 1010…. In case of data frequency is to small the ISM circuit will disable the laser because of long High- or Low-series. The ISM-circuit can be deactivated by a 25kΩ resistor from CISM to V EE. The ILM-circuit additionally is used for ac-coupled data inputs. It works as a peak detector. The laser will be disabled if data are set to a static state. The cutoff frequency of ILM fILM is defined for data pattern 1010…. (Specified value is for data input voltage swing of 400mV).The ILM-circuit is direct AC-coupled to the data input. So the cutoff frequency depends on data input swing. The ILM-circuit can be deactivated by a short from CILM to V CC.15)A capacitor within this range programs the time (or frequency).16)Open collector output for pulling up a resistor to monitor the current.17)Difference and temperature drift of passive IC component parameters match to passive IC componentparameters in other circuit parts.18)The supervisor circuit will detect a failure condition if MD voltage exceeds VMDnom±2dB range. V MDnom is given by nominal voltage level at MD which is set by V MDR. The deviation is calculated with 20lg(V MD/V MDnom).The deviation of optical power is calculated with 10lg(V MD/V MDnom).19)The supervisor circuit will detect no failure condition if MD input voltage ranges from VMDnom -1.2dB toV MDnom+1.2dB. V MDnom is given by nominal voltage level at MD which is set by V MDR. The deviation is calculated with 20lg(V MD/V MDnom). The deviation of optical power is calculated with 10lg(V MD/V MDnom). 20)A failure condition will be reported by LF=H if this condition lasts for tFDEL. Minimal capacitor on CFDEL has to be chosen that the failure recognition time is longer than the setting time of the bias controller.21)Time between LF high (or LEN high) and LDOFF high.22)At supply voltages below VCC threshold the laser diode bias and modulation current will be held disabled and LDOFF will be held high. Above the laser diode will be enabled after the Power On Delay.23)The Power On Delay is the Reset time after VCC voltage has risen above the V CC reset threshold. During the Power On Delay the Laser diode bias and modulation current will be held disabled and LDOFF will be held high.24)Temperature and voltage drift are included.25)The minimal enable pulse width time for RST=L or RSTN=H or LEN=L has to be longer then tFDEL.26)Out of amPILOT and ab PILOT a factor K=ab PILOT/am PILOT can be defined, which is an important factor for the pilot control (for definition of am PILOT and ab PILOT see Figure8). For most laser diodes the optimum value of K is 1.44 (default value). If K is set close to factor2 the modulation current and jitter may increase. If K is set close to factor 1 the modulation current may decrease. In both cases a malfunction of laser control is possible.A resistor between V CC and RMRIP can be used for decreasing am PILOT. Further a resistor between V CC andRBRIP can be used for decreasing ab PILOT. So the factor K can be adjusted. For default factor K let RBRIP and RMRIP connected to V CC (=V CCA).2.4Typical Characteristics of Temperature Compensation (Mode 1)2.4.1Modulation Current Swing versus R MOD , R TC ,Junction Temperature and Supply Voltage / High Current DriveFigure 2F =I 100°C /I 0°C versus R TC , Parameter R MOD , V CCFigure 3I 0 versus T j , Parameter R MOD , R TC (V CC =3.3V)ITD11328-5010t˚C I O 20304050607080-30-101030507090130mA2 k Ω/700 Ω2 k Ω/200 Ω2 k Ω/2 k Ω4 k Ω/200 Ω4 k Ω/700 Ω4 k Ω/2 k Ω110Figure 4I 0 versus T j , Parameter R MOD , R TC (V CC =5.0V)ITD11329-500t˚C I O-30-101030507090130mA1020304050607080100 2 k Ω/700 Ω2 k Ω/200 Ω2 k Ω/2 k Ω4 k Ω/200 Ω4 k Ω/700 Ω4 k Ω/2 k Ω1102.4.2Modulation Current Swing versus R MOD , R TC ,Junction Temperature and Supply Voltage / Low Current DriveFigure 5F =I 100°C /I 0°C versus R TC , Parameter R MOD , V CCFigure 6I 0 versus T j , Parameter R MOD , R TC (V CC =3.3V)ITD1133018001.00F 1.051.101.151.201.251.301.402800380048005800680078009800R TCk Ω5 k Ω/3.3 V5 k Ω/5 V 10 k Ω/5 V 10 k Ω/3.3 V ITD11331-505t˚C I O -30-101030507090130mA6789101112131415161810 k Ω/2 k Ω10 k Ω/5 k Ω10 k Ω/9.5 k Ω5 k Ω/5 k Ω5 k Ω/2 k Ω5 k Ω/9.5 k Ω110Figure7I0 versus T j, Parameter R MOD, R TC (V CC=5.0V)2.5Principle of Modulation Current Control by Using a Pilot Signal (Mode 2)The DC-part of the monitor current controls the bias current. The difference of the optical low frequency AC-part ∆Ppp is used for the modulation current control. ∆Ppp is measured over the monitor current. The aim of the control is to settle ∆Ppp to Zero. (That means a part of the pilot current amplitude on bias current is modulated below laser current threshold. Therefore please take into account the laser characteristics, e.g.switch-on delay, for higher data rates.) Mode 2 can only be used for DC-coupled laser diodes.Figure 8Modulation Current Control by Using a Pilot Signal2.6Data / Clock Input StageData and clock inputs are terminated with 100Ω and are connected to a V BB reference by resistors R1/R2. (V BB for Clock input is V BBC, V BB for Data input is V BBD.) This easily provides the input reference voltage at AC coupling. A schematic of the input stage is shown below:Figure9Data/Clock Input Stage 2.7Timing of Clock and DataFigure10Timing of Clock and Data ITS11334PN RINR1R2ReferenceGeneratorVBBR 1, R2= 5 kΩRIN= 100 Ω ±20%2.8Laser and V CC Supervising CircuitIf there is a laser fault (optical power deviates ±1dB) this signal is stored and indicated by LF (logic high). The fault indication (LF) can be reset with low level at RSTN or with high level at RST or with power down (V CC < V CC Reset Threshold) only. After power up,LF will always be cleared. Disabling the laser by LEN does not influence a previous fault indication by LF. The laser fault generation can be switched off by connecting CFDEL to V CC . During RSTN is logic low or RST is logic high the circuit is in Reset state.In case of changing RST =H or RSTN =L after laser fault recognition LF =H (after t FDEL ) there is an additional delay time implemented which has the same value as the Power On Delay.If the supply voltage is lower than the V CC reset threshold the indicator Hardware Alarm (HWA) is still at the low level and the circuit is in Reset state.During Power On Delay the circuit is in Reset state too. The Power On Delay is defined as the delay after V CC voltage has risen above the V CC reset threshold. This time can be adjusted by an external capacitor at COSC (Mode 1). The Reset N-Output of the MAX 809S Power Supervisor IC can be connected to RSTN to use the reset function of the MAX 809S.The laser control by RST and RSTN is fully redundant. This means only an AND combination of RST =0 / RSTN =1 can switch the laser on. The OR combination of RST =1 / RSTN =0 switches the laser off (see Table 4 for clarification).Table 4 shows the static states of these signals. Dynamic changes or delays due toexternal delay capacitors are not shown.Table 4Laser Diode Currents Enable / Disable SignalsRST LEN RSTN In Case of Laser Fault V CC < Reset Threshold V CC LDOFF Modulation Enable 1)1)Internal signal Bias Enable 1)LF (highactive)X 1X 0X 10001X X X X 1000X X 0X X 1000X X X X yes 10000011no 2)2)After Power On Delay 13)3)After t FDEL0013)01no 2)04)4)Sink current enabled = Low11Bias current is disabled by setting Bias Enable low, modulation current is disabled by setting Modulation Enable low.LEN do not effect LF. This means LF can not be reset by LEN.2.9Input Signal Monitoring and Hardware Alarm(Consideration in absence of Laser Fault)Table5Function of ISM Circuit and Hardware Alarm Indicator (HWA)Data Level (after delay of ISM)V CC < ResetThreshold of V CC/Circuit in ResetstateISM LaserEnable1)1)Internal signal LDOFF HWA (lowactive)ModulationEnable1)BiasEnable1)Constant High No01000 Constant Low No01000 Constant High Yes01000 Constant Low Yes01000 Duty Cycle ok Yes11000 Duty Cycle ok No102)2)Sink current enabled = Low111。
