PSMN3R5-40YSBX-VB Product details
Back to previous pageProduct introduction：
PSMN3R5-40YSBX-VB is a Single N-MOS deeply optimized for low-voltage, high-current power switching scenarios. The Trench process combines ultra-low on-resistance with high switching speed. The LFPAK56 package achieves an excellent balance between heat dissipation and board space. With a 40V withstand voltage, 100A current-carrying capacity, and 2mΩ-level on-resistance, it is an ideal choice for high-power applications such as server power supplies, motor drives, and battery protection, especially suitable for systems with stringent requirements on thermal resistance and current density.
