Product Description

Product Overview

The DTC144E series is a family of NPN digital transistors featuring built-in biasing resistors (R1 = R2 = 47k). This integrated design simplifies circuit configuration, allowing for inverter circuits without external input resistors and making on/off condition setting straightforward for easy circuit design. These transistors are suitable for applications such as inverters, interfaces, and drivers. Complementary PNP types are available in the DTA144E series.
