Product Overview

The DTA143Z series is a PNP digital transistor featuring built-in bias resistors (R1 = 4.7k, R2 = 47k). This integration simplifies circuit design by eliminating the need for external input resistors, enabling easy configuration of inverter circuits. Designed for straightforward operation, users only need to set the on/off conditions. The DTA143Z series is suitable for inverter, interface, and driver applications.
