p8?1/3 ? features 1) built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 2) the bias resistors consist of thinfilm resistors with complete isolation to allow positive biasing of the input. 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. structure pnp digital transistor (with built-in resistors) equivalent circuit DTA143EKA dta143eca absolute maximum ratings(t a =25 c) parameter symbol limits unit supply voltage v cc ?50 v input voltage v in ?30~+10 v output current i o ?100 ma i c(max.) ?100 power dissipation p d 200 mw junction temperature t j 150 c storage temperature t stg ?55~+150 c digital transistors (built-in resistors) 2.9 + 0.2 1.9 + 0.2 0.95 + 0.95 (1) (2) (3) + 0.2 1.6 - 0.1 2.8 + 0.2 + 0.1 0.4 - 0.05 + 0.1 0.15 - 0.06 + 0.2 1.1 - 0.1 0.8 + 0.1 0 ~ 0.1 0.3 ~ 0.6 (1) gnd (2) in (3) out all terminals have same dimensions 2.9 + 0.2 1.9 + 0.2 0.95 + 0.95 (1) (2) (3) + 0.2 1.3 - 0.1 2.4 + 0.2 + 0.1 0.4 - 0.05 + 0.1 0.15 - 0.06 + 0.2 0.95 - 0.1 0.45 + 0.1 0 ~ 0.1 (1) gnd (2) in (3) out all terminals have same dimensions out gnd(+) out r1 r2 gnd(+) in in DTA143EKA dta143eca 0.2min eiaj: sc? 59 eiaj: sot? 23
