LL4148 — Small Signal Diode January 2016LL4148Small Signal DiodeOrdering InformationAbsolute Maximum Ratings (1), (2)Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at T A = 25°C unless otherwise noted.Notes:1.These ratings are based on a maximum junction temperature of 200°C.2.These are steady-state limits. Fairchild Semiconductor should be consulted on applications involving pulsed or low-duty-cycle operations.Part NumberDevice Marking Package Packing Method LL4148Color Band Marking SOD-80 2L Tape and Reel, 7 inch Reel, 2500 pcs SymbolParameter Value Unit V RRMMaximum Repetitive Reverse Voltage 100V I F(AV)Average Rectified Forward Current 200mA I fRecurrent Peak Forward Current 500mA I FSMNon-Repetitive Peak Forward Surge Current Pulse Width = 1.0 s 1.0A Pulse Width = 1.0 μs 2.0T STGStorage Temperature Range -65 to +200°C T J Operating Junction Temperature Range -55 to +175°C COLOR BAND MARKING1ST BANDBlackThe 1st Band indicates the cathode bandSOD80Cathode BandElectrical CharacteristicsValues are at T A = 25°C unless otherwise noted.Symbol Parameter Conditions Min.Max.UnitV R Breakdown Voltage I R = 100 μA100V I R = 5.0 μA75V F Forward Voltage I F = 10 mA 1.0VI R Reverse Leakage V R = 20 V25nA V R = 20 V, T A = 150°C50μAC T Total Capacitance V R = 0, f = 1.0 MHz 4.0pFt rr Reverse Recovery Time I F = 10 mA, V R = 6.0 V (60 mA),I rr = 1.0 mA, R L = 100 Ω4.0ns。
