MJE13003 NPN Transistor – 2A 400V

The MJE13003 is a high-voltage NPN bipolar junction transistor designed for medium-current switching and power control applications. It supports a collector-emitter voltage of up to 400V and continuous collector current up to 2A, making it ideal for off-line switching power supplies, inverters, ballast circuits, and high-voltage driver stages. With fast switching performance, low saturation voltage, and strong thermal handling in a TO-220 package, the MJE13003 is widely used in SMPS designs and power electronics.
