ONSEMI MJF44H11G Power Transistor

The MJF44H11G is a high-performance NPN power transistor designed for use in switching and amplification applications. It features low collector-emitter saturation voltage of 1.0 V at 8.0 A, fast switching capabilities, and comes in a Pb-free TO-220 package suitable for isolated applications. Its maximum collector-emitter voltage is 80 V with a collector current of 10 A continuous, peak 20 A. The device has a total power dissipation of 36 W at 25°C and thermal resistance junction-to-ambient of 62.5°C/W, making it ideal for power regulation, converters, and switching stages.
