digital transistors (built-in resistors) DTD123YUA digital transistor (npn) features z built-in bias resistors enable the configuration of an inverter circui t without connecting external input resistors(see equivalent circuit) z the bias resistors consist of thin-film resistors with complete isolat ion to allow negative biasing of the input.they also have the advantage of almost completely eliminating parasitic effects z only the on/off conditions need to be se t for operation, making device design easy pin connenctions, marking and equivalent circuit DTD123YUA sot-323 1. in 2. gnd 3. out marking:f62 equivalent circuit maximum ratings(ta=25 unless otherwise noted) symbol parameter limit unit v cc supply voltage 50 v v in input voltage -5 +12 v i o output current 500 ma p d power dissipation 200 mw t j junction temperature 150 t stg storage temperature -55 +150 electrical characteristics (ta=25 unless otherwise specified) parameter symbol conditions min typ max unit v i(off) v cc =5v,i o =100a 0.3 v input voltage v i(on) v o = 0.3v,i o =20ma 2 v output voltage v o(on) i o /i i =50ma/2.5ma 0.1 0.3 v input current i i v i =5v 3.6 ma output current i o(off) v cc =50v,v i =0v 0.5 a dc current gain g i v o =5v,i o =50ma 56 input resistance r 1 1.54 2.2 2.86 k ? resistance ratio r 2 /r 1 3.6 4.5 5.5 transition frequency f t v o =10v,i o =5ma,f=100mhz 200 mhz 1 of 1 4008-318-123 sales@twtysemi.com http://www.twtysemi.com product specification
