DTC614TU / DTC614TK is a digital transistor produced by Toshiba Corporation. Its characteristic is that it integrates resistors, which makes it suitable for use at high current levels.
The DTC614TU (and DTC614TK) are NPN digital transistors with a built‑in resistor, designed for low‑saturation‑voltage applications such as muting circuits. They support collector currents up to 600 mA and feature a typical VCE(sat) of 40 mV at Ic/IB = 50 mA/2.5 mA.
The datasheet lists absolute maximum ratings, electrical parameters, and package dimensions for the UMT3 and SMT3 surface‑mount packages. It also includes characteristic curves for current gain, saturation voltage, and ON resistance, as well as a disclaimer and export‑control information.
