Description
The MJ10009 is a high-voltage, high power NPN silicon Darlington transistor engineered for robust performance in inductive switching circuits where fall time and reliability are critical. It is capable of handling up to 500 V collector-emitter voltage, 20 A continuous collector current, and 175 W power dissipation. Housed in a TO-3 metal can package with flange mount, it is suited for industrial power supply, motor drive, inverter and switching regulator applications.
