Product Description

Product Overview

DTA143E series are PNP digital transistors with built-in biasing resistors (R1 = R2 = 4.7k). These transistors simplify circuit design by eliminating the need for external input resistors, enabling inverter circuit configurations with easy on/off condition settings. They are suitable for inverter, interface, and driver applications. Complementary NPN types are available in the DTC143E series.
