DTA115TM / DTA115TE / DTA115TUA / DTA115TKA are digital transistors produced by ROHM, which have built-in bias resistors and can be configured as inverter circuits without connecting external input resistors.
The DTA115TUA is a -100 mA / -50 V digital transistor with built‑in bias resistors, offered by ROHM. This datasheet presents its electrical characteristics, packaging options, and typical application circuits.
Key features include built‑in thin‑film resistors for biasing, high isolation, and the ability to achieve higher mounting densities. The device is intended for inverter, interface, and driver circuits in audio‑visual, office‑automation, communication, and consumer electronics.
