The DTC143TKA is an NPN digital transistor with built-in bias resistors, designed for switching, inverter, interface, and driver circuits. It is packaged in SOT-346 (SC-59) with a maximum collector-emitter voltage of 50 V, collector current of 100 mA, and power dissipation of 200 mW. The input resistance is 4.7 kΩ, and the collector-emitter saturation voltage is up to 0.15 V at 5 mA collector current and 0.25 mA base current. The device has a DC current gain (hFE) range of 100 to 600 at 1 mA collector current and 5 V collector-emitter voltage. Junction temperature operates up to 150 °C, and storage temperature ranges from -55 °C to +150 °C. The part is RoHS compliant and meets lead-free requirements.
