DTC143ZCA

DTC143Zxx Series Digital Transistors (NPN)(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 complete -ly eliminating parasitic effects • Only the on/off conditions need to be set for operation, making device design easy 2.MA xIMUM RATINGS (Ta=25℃ unless otherwise noted) Symbol Parameter Limits(DTC143Z xx) M CA UA E Unit SA KA Supply Voltage VCC 50 V Input Voltage VIN -5~+30 V Output Current IO 100 mA Power Dissipation PD Operation Junction and Storage Temperature Range 100 150 200 Tj ,Tstg 200 mW 300 200 -55~+150 ℃ 3.
