Product Description
Product Overview
The DTA143Z series is a family of PNP digital transistors 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, these transistors only require setting the on/off conditions. They are suitable for applications such as inverters, interfaces, and drivers. Complementary NPN types are also available in the DTC143Z series.
