DTA143TM / DTA143TE / DTA143TUA DTA143TKA / DTA143TSA Transistors Digital transistors (built-in resistor) DTA143TM / DTA143TE / DTA143TUA DTA143TKA / DTA143TSA !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 thin-film 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. !Equivalent circuit C B R1 E B : Base C : Collector E : Emitter !Structure PNP digital transistor (Built in resistor type) !External dimensions (Units : mm) DTA143TM 1.2 0.8 0.2 DTA143TE 0.2 1.6±0.2 (1) Base (2) Emitter (3) Collector Abbreviated symbol : 93 0.7±0.1 +0.1 0.2−0.05 (2) (3) 0.55±0.1 +0.1 0.3 −0.05 ROHM : EMT3 0~0.1 (1) Emitter (2) Base (3) Collector 0.1Min. 0.22 0.5 0.13 0~0.1 ROHM : VMT3 (1) 0.15Max. 0.5 0.5 0.8±0.1 +0.1 0.2−0.05 (1) 1.6±0.2 0.8 (3) 0.4 0.4 1.2 0.32 1.0±0.1 (2) 0.15±0.05 Abbreviated symbol : 93 DTA143TKA 2.0±0.2 0.65 0.65 1.6+0.2 −0.1 0~0.1 ROHM : SPT EIAJ : SC-72 3Min. 0.15 0.45+ −0.05 0.4 2.5 + −0.1 (1) (2) (3) 0.5 +0.1 0.15 −0.06 0.4 +0.1 −0.05 All terminals have same dimensions 0.15 0.45 + −0.05 (1) Emitter (2) Collector (3) Base 0.3Min.
