Before using this document, please confirm that this is the latest version.Not all devices/types available in every country. Please check with local NEC representative for availability and additional information.The 2S2M and 2S4M are P-gate fully diffused mold SCRs with an average on-current of 2 A. The repeat peak off-voltages (and reverse voltages) are 200 V and 400 V.FEATURES•This transistor is designed for high-speed switching and is deal for use in commercial frequencies, high-frequency pulse applications, and inverter applications.•This transistor features a small and lightweight package and is easy to handle even on the mounting surface due to its TO-202AA dimensions.

ERROR CONDITIONSa).Error DetectionSystem errors occur when:i)The integral part of any calculation result exceeds16digits.ii)The integral part of any memory calculation result exceeds8-digit or when the integral part of any addendor subtrahend to memory exceeds8-digit.iii)The integral part of a mark-up and markdown calculation result exceeds8-digit.iv)A division by zero is attempted.v)An extraction of the square root of a negative number is attempted.Rough Estimate Calculation results occur when:The integral part of the result of any one of the standard four functions,percentage,square,reciprocal,and power calculations exceeds8-digit and is equal to16-digit or less.b).Error Indicationi)System error:"0”is indicated in the first-digit position and"E"in the sign-digit position.ii)Rough Estimate Calculation result:SilanSemiconductorsSC3423HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTDRev:1.02000.12.318The high-order8-digit of a calculation result is indicated together with"E".The location of the decimalpoint corresponds to the result of calculation times le-8,and no zero shift is performed.c).Error Releasei)System error:A system error can be released by depressing ON/AC key.ii)Rough Estimate Calculation result:A rough estimate calculation error can be released by depressing theON/AC or CE/C key.However the calculation result is not cleared by CE/C key but is retained.4. OPERATION CHARACTERISTICSa)Constant OperationThe SC3423has implied constant mode on+,-,x,÷,&,%operations.The constant is performed automatically by the"="key,"%"key,or"%"key without a constant for addition,subtraction and division while the first operand is the constant for multiplication.b)Number EntryNumbericals can be entered up to8-digit.Entries equal to9-digit or more are ignored.c)Memory ProtectionIn any error detection,the memory contents present before the error detection are protected.d)Memory IndicationIf the memory contents are a number other than zero,"M"is indicated in the sign-digit position.e)Auto Power OffIf no key is depressed for a specific period of time,the power supply will automatically turn off.This time interval up to power-off is131,072words(Approximately equal to14minutes and24seconds at Fd=52Hz, the display time of a word being equal to6ms when Fd=52Hz).3V1.5V0VOutput waveform examplef)Double Key DepressionThe order of priority,when two keys are depressed simultaneously is as follows:OFF->ON/AC->CE/C->5->6->4->ROM->·->9>M+->=->+/-->CE->+->M-->%->RMx<-<-<-0<-1<-3<-2<-CM<-7<-8<--<··g)Key Bounce Protection-Font edge:Down to l word and up to about3words.-Back edge:14words.SilanSemiconductorsSC3423HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTDRev:1.02000.12.3195.
