Rochester Electronics TRANSISTORS - Transistors (BJT) - Single - 2SD2161-AZ 2SD2161-AZ

The 2SD2161 is an NPN silicon epitaxial Darlington power transistor designed for low-frequency power amplification and low-speed switching in applications such as motor and solenoid drivers. It is housed in an isolated TO-220 package. The device has a collector-emitter voltage rating of 100 V, a collector current rating of 5.0 A DC, and a total power dissipation of 2.0 W at 25°C ambient temperature. The DC current gain is at least 2,000 at a collector-emitter voltage of 2.0 V and collector current of 2.0 A. It is classified as Standard quality grade for use in consumer, industrial, and office equipment.
