DTD123TK is an NPN digital transistor with built-in bias resistors, designed for switching, inverter, and interface circuits. It is packaged in an SOT-346 (SC-59) case and supports a maximum collector-emitter voltage of 40 V and collector current of 500 mA. The transistor has a collector-emitter saturation voltage of up to 0.3 V at a collector current of 50 mA and a DC current gain (hFE) ranging from 100 to 600 at 50 mA. It includes a 2.2 kΩ input resistor and is RoHS compliant. The junction temperature range is -55 °C to 150 °C, with a maximum power dissipation of 200 mW. Complementary PNP type DTB123TK is available.
