This document describes the features and characteristics of the DTA023J series PNP digital transistors produced by ROHM. These transistors have built-in bias resistors, allowing the configuration of an inverter circuit without connecting external input resistors. The bias resistors are made of thin-film resistors with complete isolation, allowing negative biasing of the input and eliminating parasitic effects. Only the on/off conditions need to be set for operation, making circuit design easy. They are suitable for switching circuits, inverter circuits, interface circuits, and driver circuits.
The DTA023JM is a PNP digital transistor in the DTA023J series featuring built‑in bias resistors, allowing simple inverter or switching circuit designs without external resistors. It complies with RoHS and lead‑free requirements and is intended for general‑purpose electronic equipment.
The document provides absolute maximum ratings, electrical characteristics, package dimensions, and application examples such as switching, inverter, interface, and driver circuits. Packaging options include VMT3 (1212) for the DTA023JM part.
