DTC125TUA / DTC125TKA is a digital transistor from ROHM with a built-in resistor of R1=200kΩ, which can be used for applications such as inverters, interfaces, and drivers.
The DTC125TUA is a 100 mA / 50 V NPN digital transistor with an integrated thin‑film bias resistor, designed for inverter, interface and driver applications. Its built‑in resistor allows negative biasing of the input and eliminates parasitic effects, simplifying circuit design.
Key features include built‑in bias resistors for easy inverter configuration, high mounting density, and a planar silicon structure. The device is supplied in a tape‑and‑reel package (UMT3/SMT3) and is intended for use in general‑purpose electronic equipment such as audio‑visual, office‑automation, communication devices and consumer electronics.
