The BUW46 is a high-voltage NPN power transistor designed for demanding applications. It offers a robust 450V collector-emitter breakdown voltage (BV CEO ) and can handle a continuous collector current of up to 15A, with a peak collector current capability of 30A. The device is rated for 175W of power dissipation, making it suitable for power switching and amplification circuits.
Packaged in a TO-3 case, the BUW46 is designed for through-hole mounting. Key electrical characteristics include a typical base-emitter saturation voltage of 1.4V and a typical collector-emitter saturation voltage of 1.5V. Switching characteristics are also notable, with a turn-on time of 750ns and a fall time of 800ns.
With a wide operating junction and storage temperature range from -65°C to 200°C, the BUW46 is built for reliability in harsh environments. Its high voltage and current ratings make it a suitable component for power supply designs, industrial controls, and other high-power applications where dependable performance is critical.
