BU931P is an NPN Darlington transistor manufactured by STMicroelectronics. It features a minimum collector-emitter breakdown voltage of 400V, maximum collector current of 15A, and maximum power dissipation of 135W. The DC current gain (hFE) is at least 300 at Ic=5A and Vce=10V, and the collector-emitter saturation voltage is 1.8V maximum at Ib=250mA and Ic=10A. The device has a maximum junction temperature rating of 175°C.
The Darlington configuration provides high current gain, making the BU931P suitable for high-power switching applications such as motor control, power inverters, and relay drivers. The transistor is mounted in a TO-247-3 through-hole package, which offers good thermal performance for heat sink attachment.
The component is RoHS3 compliant, MSL level 1 (unlimited), and REACH unaffected, though these compliance statuses are unverified from a datasheet. No datasheet is currently linked for this part.
