DTB123TK is a PNP digital transistor with built-in bias resistor (R1 = 2.2 kΩ) in an SOT-346 package, designed for inverter, interface, and driver applications. It has a collector-emitter voltage rating of -40 V, a collector current rating of -500 mA, and a power dissipation of 200 mW. The device features a DC current gain (hFE) of 100 to 600 at -50 mA collector current and a collector-emitter saturation voltage of up to 300 mV. The junction temperature range is -55 °C to +150 °C. The package is surface-mounted and taped in a 180 mm reel with 3000 pieces per reel.
