BUK7J1R0-40H-VB Product details
Back to previous pageProduct introduction：
The BUK7J1R0-40H-VB is a Single N-MOS deeply optimized for low-voltage, high-current power switch applications. The SGT (Shielded Gate Trench) process balances ultra-low conduction losses with excellent switching characteristics. The LFPAK56 package achieves an excellent balance between thermal resistance, parasitic inductance, and board footprint. The combination of 40V withstand voltage, 150A current capability, and 0.7mΩ on-resistance makes it an ideal choice for high-power-density power supplies, motor drives, and battery protection applications, especially suitable for systems with stringent requirements for high efficiency and miniaturization.
