DTC114GUA/DTC114GKA is a digital switch transistor launched by ROHM. It has an integrated bias resistor, which can realize negative bias input, small parasitic effects, and is easy to design. It is suitable for switching power supplies, interface circuits, and driver circuits.
The DTC114GUA and DTC114GKA are 100 mA, 50 V digital transistors that incorporate a thin‑film bias resistor, allowing negative input biasing while minimizing parasitic effects. They are offered in compact surface‑mount packages (UMTS/SMT3 and tape‑and‑reel) for high‑density mounting in inverter, interface, and driver circuits.
Key specifications include collector‑base and collector‑emitter breakdown voltages of 50 V, an emitter‑base rating of 5 V, a maximum collector current of 100 mA, and a power dissipation limit of 200 mW. The device operates up to a junction temperature of 150 °C and is supplied in standard semiconductor packaging formats.
