Product Description

Product Overview

The DTA123E series are PNP digital transistors with built-in biasing resistors, designed for simplified inverter circuit configurations. These transistors feature integrated R1 and R2 resistors (2.2k each), eliminating the need for external input resistors and streamlining circuit design. Ideal for applications requiring easy on/off condition setting, they are suitable for use as inverters, interfaces, and drivers. Complementary NPN types are available in the DTC123E series.
