BUK6208-40C,118-VB Product details
Back to previous pageProduct introduction：
BUK6208-40C,118-VB is a Single N-MOS deeply optimized for low-voltage, high-power switching scenarios. Trench technology balances extremely low conduction loss with fast switching capability, and the TO252 (DPAK) package achieves an ideal balance between heat dissipation performance and mounting area. The combination of 40V withstand voltage, 85A current-carrying capacity, and 5mΩ on-resistance makes it a cost-effective preferred device for applications such as high-density power conversion, motor drives, and battery protection, especially suitable for industrial-grade and automotive-grade systems requiring high current handling and low heat generation.
