ROHM DTC143TUAT106 NPN Digital Transistor Featuring Built in Bias Resistors for Switching and Interface

Product Overview

The DTC143T series are NPN digital transistors featuring built-in biasing resistors, simplifying circuit design by eliminating the need for external input resistors. These transistors are ideal for configuring inverter circuits and offer advantages such as complete isolation for negative biasing and elimination of parasitic effects. They are suitable for switching, inverter, interface, and driver circuits. Complementary PNP types and complex transistor configurations are also available.
