Product Description

Product Overview

The ROHM DTC143E series are NPN digital transistors with built-in bias resistors, designed for simplified circuit configurations. These transistors feature integrated resistors (R1 = R2 = 4.7k) that eliminate the need for external input resistors, enabling inverter circuit designs with just on/off condition settings. Ideal for applications requiring easy circuit design, such as inverters, interfaces, and drivers, the DTC143E series offers convenient operation and design flexibility. Complementary PNP types are also available in the DTA143E series.
