BUK9237-55,118-VB Product details
Back to previous pageProduct introduction：
BUK9237-55,118-VB is a Single N-MOS deeply optimized for medium and low-voltage power switching scenarios. Its Trench technology balances low switching losses with high reliability, and the TO252 (DPAK) package strikes a balance between heat dissipation capability and mounting area. The combination of 60V withstand voltage, 45A current-carrying capacity, and 25mΩ on-resistance makes it an ideal cost-effective choice to replace traditional DPAK packaged devices, especially suitable for high-volume applications such as motor drives, power conversion, and vehicle systems.
