The DTC643TK is an NPN digital transistor with a built-in 4.7 kΩ resistor, designed for low saturation voltage applications such as muting circuits. It is packaged in the SMT3 (SC-59) case, measuring 2.9 mm × 1.9 mm × 1.1 mm. The device supports a maximum collector current of 600 mA and collector-emitter voltage of 20 V, with a collector power dissipation of 200 mW. It exhibits a typical collector-emitter saturation voltage of 40 mV at IC/IB = 50 mA / 2.5 mA and a DC current gain (hFE) range of 820 to 2700 at VCE = 5 V and IC = 50 mA. The junction temperature rating is 150 °C, and it operates within a storage temperature range of -55 °C to +150 °C. The part is supplied in tape packaging with a basic ordering unit of 3000 pieces.
