ROHM DTC124XUAFRAT106 Digital NPN Transistor Featuring Built in Bias Resistors for Interface Applications

Product Overview

The ROHM DTC124XUA FRA is a digital NPN transistor featuring built-in biasing resistors (R1 = 22k, R2 = 47k) that simplify inverter circuit configuration without external input resistors. This design facilitates easy circuit design by only requiring the setting of on/off conditions. It is AEC-Q101 Qualified and suitable for applications such as inverters, interfaces, and drivers. Complementary PNP types are also available (DTA124XUA FRA).
