The STMicroelectronics BU931T is an NPN Darlington bipolar junction transistor designed for high-voltage and high-current applications. This component features a collector-emitter breakdown voltage of 400 V and a maximum continuous collector current of 10 A. With a power dissipation capability of 125 W and a junction temperature rating of 175°C, it is suitable for demanding thermal environments. The BU931T offers a minimum DC current gain (hFE) of 300 at 5A collector current and 10V collector-emitter voltage. Its saturation voltage (Vce Sat) is a maximum of 1.8V at 250mA base current and 10A collector current. This device is presented in a TO-220-3 through-hole package, facilitating robust mounting. The BU931T is qualified to AEC-Q101 standards, indicating its suitability for automotive applications.
