Product Description
Product Overview
The DTA115E series are PNP digital transistors with built-in bias resistors, designed for simplified circuit configurations. Featuring integrated R1 and R2 resistors (100k each), these transistors enable the implementation of inverter circuits without external components, making circuit design easier. They are suitable for applications requiring simple on/off condition control, such as inverters, interfaces, and drivers. Complementary NPN types are also available in the DTC115E series.
