Product Description

Product Overview

The ROHM DTC123E series is a range of NPN digital transistors featuring built-in biasing resistors (R1 = R2 = 2.2k). This integrated design simplifies circuit configuration, allowing for inverter circuits without external input resistors, thereby easing circuit design by focusing solely on on/off conditions. These transistors are suitable for inverter, interface, and driver applications. Complementary PNP types are available in the DTA123E series.
