BDW93CFP

BDW93CFP Description

The BDW93CFP from STMicroelectronics is a high-performance NPN Darlington transistor designed for demanding power applications. Encased in a robust TO220FP package, it delivers a collector-emitter voltage (Vce) of 100V and a maximum collector current (Ic) of 12A, making it suitable for high-current switching and amplification tasks. With a power dissipation of 33W and an operating junction temperature (TJ) of 150°C, this transistor excels in thermally challenging environments. Its low collector cutoff current (1mA max) and high DC current gain (hFE ≥ 750 @ 5A, 3V) ensure efficient operation with minimal leakage.
