BUX48A Description

Short technical summary and product information.

The SPTECH BUX48A is a silicon NPN power transistor designed for demanding high-voltage and high-speed power switching applications. It features a high collector-emitter voltage capability of up to 1000V (VCEX) and a continuous collector current rating of 15A.

This transistor is particularly suited for line-operated switchmode applications such as switching regulators, inverters, solenoid and relay drivers, motor controls, and deflection circuits where fast switching speed and critical fall times are essential. Its robust design includes a maximum power dissipation of 175W at 25℃ case temperature and a junction temperature up to 200℃.

The BUX48A comes in a TO-3 package, suitable for through-hole mounting. Key electrical characteristics include a collector-emitter saturation voltage of 5.0V at 12A/2.4A and a DC current gain (hFE) of 8 at 8A/5V. Its fast switching times, including a fall time of 0.4μs, make it ideal for applications requiring efficient power conversion and control.
