This document describes the features and characteristics of the DTA044T series PNP digital transistors produced by ROHM Co., Ltd., including built-in bias resistors, elimination of parasitic effects, and easy circuit design. These transistors are suitable for switching circuits, inverter circuits, interface circuits, and driver circuits.
The DTA044T series from ROHM are PNP digital transistors that incorporate built‑in bias resistors, allowing inverter or driver circuits without external resistors. The series includes variants DTA044TM, DTA044TEB and DTA044TUB, all RoHS‑compliant and offered in tape‑reel packaging.
The document lists absolute maximum ratings, typical electrical characteristics such as collector‑emitter voltage of –50 V and collector current of –60 mA, as well as mechanical dimensions for each package type. Packaging specifications, dimension tables and application notes for switching, inverter and interface circuits are also provided.
