BUX44 Description

Short technical summary and product information.

The BUX44 is an NPN Darlington transistor manufactured by Harris Semiconductor. It features a collector-emitter breakdown voltage of 400V and a continuous collector current rating of 8A, making it suitable for high-voltage switching and amplification applications. The device dissipates up to 120W of power and has a transition frequency of 8MHz.

 

Housed in a TO-204AA (TO-3) through-hole package, the BUX44 offers robust mechanical mounting for power circuits. The Darlington configuration provides high current gain, reducing the drive current required from preceding stages.

 

This transistor is designed for use in power supply circuits, motor controllers, and other industrial applications where high voltage and moderate current switching are required. The TO-3 metal package ensures efficient heat transfer when mounted to a suitable heatsink.
