Simplify circuit design with ROHM DTC143TKAT146 NPN digital transistor featuring built in bias resistors

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 inverter circuits, switching circuits, interface circuits, and driver circuits. The integrated thin-film resistors offer complete isolation for negative biasing and eliminate parasitic effects, making circuit design straightforward by only requiring the setting of on/off conditions. Complementary PNP types (DTA143T series) and complex transistor configurations are also available.
