The DTC143XUB is an NPN digital transistor with built-in bias resistors, designed for inverter, interface, and driver applications. It is packaged in the UMT3F surface-mount case, measuring 2.0mm × 2.1mm. The device has a maximum collector current of 100mA and a collector-emitter voltage rating of 50V. Power dissipation is rated at 200mW. The input resistance R1 is 4.7kΩ with a resistance ratio R2/R1 of 2.1. It operates with a junction temperature up to 150°C and storage temperature from -55°C to +150°C. Complementary PNP types are available in the DTA143X series.
