PSMN3R2-40YLBX-VB Product details
Back to previous pageProduct introduction：
PSMN3R2-40YLBX-VB is a Single N-MOS deeply optimized for low-voltage, high-current power switching scenarios. The Trench process achieves an excellent balance between extremely low on-resistance and efficient switching characteristics. The LFPAK56 package strikes an optimal balance between heat dissipation capability and board space. With a 40V withstand voltage, 100A current-carrying capacity, and 2mΩ-level on-resistance, it is an ideal high-performance alternative to traditional DPAK or D2PAK package devices, especially suitable for applications requiring high power density and high reliability.
