BUK964R1-40E,118-VB Product details
Back to previous pageProduct introduction：
BUK964R1-40E,118-VB is a Single N-MOS deeply optimized for low-voltage, high-power switching scenarios. The Trench process balances ultra-low on-resistance with high switching speed, while the TO263 package provides excellent heat dissipation and current-carrying capability. The combination of 40V withstand voltage, 150A current-carrying capability, and 2mΩ-level on-resistance makes it an ideal choice for high-current-density power paths, motor drives, and battery management systems, especially suitable for industrial-grade applications with stringent requirements for loss and temperature rise.
