This document describes the features and characteristics of the DTA123E series PNP digital transistors produced by ROHM. These transistors have built-in bias resistors, making it easy to configure inverter circuits without external input resistors. They completely eliminate parasitic effects and can be easily designed by setting the on/off conditions. The DTC123E series complementary NPN types are also available. These transistors are suitable for switching circuits, inverter circuits, interface circuits, and driver circuits.
The DTA123EE is a PNP digital transistor with built‑in biasing resistors (2.2 kΩ) that simplify inverter and switching circuit designs. It offers lead‑free/RoHS compliance and is available in several package types such as SOT‑323, SOT‑346, and SOT‑416.
Typical applications include switching circuits, inverter circuits, interface circuits, and driver circuits. The datasheet lists absolute maximum ratings, detailed electrical characteristics, and mechanical dimensions for each package variant.
