Product Overview

The DTA144E series is a PNP digital transistor featuring built-in biasing resistors (R1 = R2 = 47k). This integrated design simplifies circuit configuration, enabling the creation of inverter circuits without external input resistors. Ideal for applications requiring easy circuit design and straightforward on/off condition setting, this series is suited for inverter, interface, and driver functions. Complementary NPN types are available in the DTC144E series.
