DTC143ECA digital transistor (npn) features 1) built-in bias resistors enable the configurati on of an inverter circuit without connecting external input resistors (see equivalent circuit). 2) the bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the inpu t. they also have the advantage of almost completely eliminating parasitic effects. 3) only the on/off conditions need to be set for operation, making device design easy. pin connenctions and marking sot-23 addreviated symbol: 23 absolute maximum ratings(ta= 25 ) limits (dtc143e ca ) parameter symbol unit supply voltage v cc 50 v input voltage v in -10~+30 v i o 100 output current i c(max) 100 ma power dissipation pd 200 mw junction temperature t j 150 storage temperature tstg -55~150 electrical characteristics (ta=25 ) parameter s ymbol min. typ max. unit conditions v i(off) 0.5 v cc =5v ,i o =100a input voltage v i(on) 3 v v o =0.3v ,i o =20 ma output voltage v o(on) 0.3 v i o /i i =10ma/0.5ma input current i i 1.8 ma v i =5v output current i o(off) 0.5 a v cc =50v ,v i =0 dc current gain g i 2 0 v o =5v ,i o =10ma input resistance r 1 3.29 4.7 6.11 k ? resistance ratio r 2 /r 1 0.8 1 1.2 transition frequency f t 250 mhz v o =10v ,i o =5ma,f=100mhz l e a d(p b)- f r ee p b weitron http://ww w .weitron.com.tw 1/ 3 08 -jun-07
