The BU941P is an NPN Darlington power transistor manufactured by STMicroelectronics. It is designed for high-voltage switching applications, particularly electronic ignition systems. The device integrates an antiparallel collector-emitter diode for improved ruggedness.
Key electrical ratings include a maximum collector-emitter voltage (VCEO) of 400V, a collector-emitter voltage with base shorted (VCES) of 500V, and a continuous collector current of 15A (peak 30A). The DC current gain (hFE) is a minimum of 300 at IC=5A, VCE=10V. Collector-emitter saturation voltage is typically 1.6V at IC=8A, IB=100mA.
The BU941P is housed in a TO-247-3 through-hole package, offering a maximum power dissipation of 155W at case temperature 25°C. The operating junction temperature ranges up to 175°C, with a thermal resistance junction-to-case of 0.97°C/W.
Typical applications include high-voltage ignition coil drivers and high-ruggedness electronic ignition systems. The device is suitable for inductive load switching due to its robust design and switching characteristics, with storage time up to 15µs and fall time as low as 0.5µs.
