Product Description
Product Overview
The DTA123Y series is a range of PNP digital transistors featuring built-in biasing resistors (R1 = 2.2k, R2 = 10k). This integrated design simplifies circuit configuration, enabling inverter circuits without external input resistors. Ideal for applications requiring easy on/off condition setting, the DTA123Y series is suitable for inverter, interface, and driver functions. Complementary NPN types are available in the DTC123Y series.
