The DTD543ZE is an NPN digital transistor with built-in bias resistors in an SOT-416 (EMT3) package, designed for inverter, interface, and driver applications. It has a maximum collector current of 500 mA and a supply voltage rating of 12 V. The input resistor R1 is 47 kΩ and R2 is 4.7 kΩ, with a resistance ratio of 10. The transistor exhibits a maximum collector-emitter saturation voltage of 300 mV at an output current of 100 mA and input current of 5 mA. Power dissipation is rated at 150 mW, and the junction temperature range extends to 150 °C. The device supports negative biasing and minimizes parasitic effects through thin-film resistor isolation.
