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 -40 --- 10 v i o i c(max) output current --- -30 -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 =-0.2v, i o =-5ma) -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) --- --- -0.36 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) 56 --- --- r 1 input resistance 15.4 22 28.6 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-323 suggested solder pad layout 1.90 0 .7 0 0.90 0. 65 0.65 *marking: 15 epoxy meets ul 94 v-0 flammability rating moisure sensitivity level 1 mm 2012-0 willas electronic corp. pnp digital transistor DTA124EUA dimensions in inches and (millimeters) .056(1.40) .047(1.20) .096(2.45) .078(2.00) .004(0.10)min. .010(0.25) .003(0.08) .043(1.10) .032(0.80) .016(0.40) .008(0.20) .004(0.10)max. .087(2.20) .070(1.80) .054(1.35) .045(1.15)
