DTA143ECA

DTA143Exx Series Digital Transistors (PNP)(Built-in Resistors) 1. Features • Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors(see equivalent circuit); • 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 para sitic effects; • Only the on/off conditions need to be set for operation, making device design easy. 2.MAxIMUM RATINGS (Ta=25℃ unless otherwise noted) Symbol Parameter Limits(DTA143E xx) M CA UA E Unit SA KA Supply Voltage VCC -50 V Input Voltage VIN -30~+10 V Output Current IO -100 mA Power Dissipation PD Operation Junction and Storage Temperature Range 100 150 200 Tj ,Tstg 200 200 mW 300 -55~+150 ℃ 3.
