The DTC043XUB is an NPN digital transistor with built-in bias resistors (R1 = 4.7 kΩ, R2 = 10 kΩ) in a SOT-323FL package, rated for a collector current of 100 mA and a collector-emitter voltage of 50 V. It has a power dissipation of 200 mW and a junction temperature range of -55°C to +150°C. The device is designed for inverter, interface, and driver applications, enabling circuit simplification by eliminating the need for external input resistors. Its DC current gain is a minimum of 35 at 5 mA output current, and the output saturation voltage is 150 mV maximum at 5 mA output current and 0.5 mA input current.
