Product Description
Digital Transistors (Bias Resistor Built-in Transistors)
Product Overview
The DTC144T series are NPN digital transistors featuring built-in biasing resistors, simplifying inverter circuit configurations without external resistors. These thin-film resistors offer complete isolation for negative input biasing and eliminate parasitic effects, making circuit design easy by focusing only on on/off conditions. They are suitable for switching, inverter, interface, and driver circuits. Complementary PNP types (DTA144T series) and complex transistors are also available. This series is Lead-Free and RoHS Compliant.
