features ? built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors ? the bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. they also have the advantage of almost completely eliminating parasitic effects. ? only the on/off conditions need to be set for operation, making device design easy absolute maximum ratings @ 25 symbol parameter min typ max unit v cc supply voltage --- 50 --- v v in input voltage -10 --- 40 v i o output current --- 100 --- ma p d power dissipation --- 200 --- mw t j junction temperature --- 150 --- t stg storage temperature -55 --- 150 electrical characteristics @ 25 symbol parameter min typ max unit v i(off) --- --- 0.5 v v i(on) input voltage (v cc =5v, i o =100 a) (v o =0.3v, i o =2ma) 3.0 --- --- v v o(on) output voltage (i o /i i =10ma/0.5ma) --- --- 0.3 v i i input current (v i =5v) --- --- 0.18 ma i o(off) output current (v cc =50v, v i =0) --- --- 0.5 a g i dc current gain (v o =5v, i o =5ma) 68 --- --- r 1 input resistance 32.9 47 61.1 k r 2 /r 1 resistance ratio 0.8 1.0 1.2 f t transition frequency (v o =10v, i o =5ma, f=100mhz) --- 250 --- mhz sot-23 suggested solder pad layout .079 2.000 in ch es mm . 031 .800 .035 .900 . 037 .950 .037 .950 *marking: 26 epoxy meets ul 94 v-0 flammability rating moisure sensitivity level 1 2012- 0 willas electronic corp. npn digital transistor DTC144ECA dimensions in inches and (millimeters) .080(2.04) .070(1.78) .110(2.80) .083(2.10) .006(0.15)min. .008(0.20) .003(0.08) .055(1.40) .035(0.89) .020(0.50) .012(0.30) .004(0.10)max. .122(3.10) .106(2.70) .063(1.60) .047(1.20)
