STMicroelectronics BU941 is a high-power NPN Darlington bipolar transistor designed for demanding applications. This component features a robust 400V collector-emitter breakdown voltage and a maximum collector current capability of 15A, with a power dissipation of 180W. The device offers a minimum DC current gain (hFE) of 300 at 5A and 10V, and a saturation voltage (Vce Sat) of 2V maximum at 300mA base current and 12A collector current. It is housed in a TO-204AA (TO-3) package, suitable for chassis mounting, and operates across a wide temperature range up to 200°C (TJ). The BU941 is commonly utilized in power switching, motor control, and general-purpose amplification circuits across industrial and automotive sectors.
