DTA014TM/DTA014TEB/DTA014TUB is a digital transistor produced by ROHM company, which has a built-in resistor and can directly control the base terminal without an external resistor. The transistor adopts PNP epitaxial planar silicon transistor (resistor built-in type) structure, which can be applied to inverters, interfaces, drivers and other fields.
The DTA014TM is a PNP epitaxial planar silicon transistor with a built‑in input resistor, allowing direct voltage control of the base terminal without external components. It is intended for use in inverters, interfaces, and driver circuits.
Key features include thin‑film bias resistors for positive biasing, simplified on/off operation, and packaging options such as T2L and TL taping. The sheet lists absolute maximum ratings, electrical characteristics, and typical application circuits.
