The BUX48 is a high power NPN silicon transistor from STMicroelectronics, intended for switching and industrial applications from single and three-phase mains. It features a collector-emitter voltage (VCEO) of 400V, collector current (IC) of 15A continuous (30A peak, 55A non-repetitive peak), and a maximum power dissipation of 175W at case temperature 25°C. The device offers fast switching with typical turn-on time of 1µs, storage time of 3µs, and fall time of 0.8µs. It is housed in a TO-3 metal package (TO-204AA equivalent) with chassis mount termination. The maximum junction temperature is 200°C, and thermal resistance junction-to-case is 1°C/W. The transistor is suitable for switch mode power supplies, flyback and forward converters, and other industrial power circuits.
