Quality Control: Learn More
STMicroelectronics BUX348 is a high-power NPN bipolar junction transistor designed for demanding applications. This component features a collector-emitter breakdown voltage of 450 V and a continuous collector current capability of 45 A, with a maximum power dissipation of 300 W. The BUX348 is housed in a TO-3 (TO-204AA) package, suitable for through-hole mounting. Its high voltage and current ratings, coupled with a junction temperature capability of 200°C, make it ideal for power switching, motor control, and industrial power supplies. The saturation voltage is specified at 900mV at 6A base current and 30A collector current, ensuring efficient operation.
