They also have the advantage of almost completely eliminating parasitic effects. 3) Only the on / off conditions need to be set for operation, making the device design easy. 0.8 (3) 0.3Min. zApplications Inverter, Interface, Driver B Package SMT3 Packaging type Taping Code T146 Basic ordering unit (pieces) 3000 R1 E B : Base C : Collector E : Emitter DTD143TK R1=4.7kΩ zAbsolute maximum ratings (Ta=25°C) Parameter Symbol Limits Unit Collector-base voltage VCBO 50 V Collector-emitter voltage VCEO 40 V Emitter-base voltage VEBO 5 V Collector current IC 500 mA Collector power dissipation PC 200 mW Junction temperature Tj 150 C Storage temperature Tstg −55 to +150 C Rev.B 1/2 DTD143TK Transistors zElectrical characteristics (Ta=25°C) Parameter Symbol Min.
