PSMNR70-40YSN-VB Product details
Back to previous pageProduct introduction：
The PSMNR70-40YSN-VB is a Single N-MOS deeply optimized for low-voltage, high-power switching applications. Using advanced SGT technology, it combines extremely low conduction losses with excellent switching characteristics. The LFPAK56 package achieves an ideal balance between heat dissipation and board space. The combination of 40V withstand voltage, 150A continuous current, and 0.7mΩ ultra-low on-resistance makes it a preferred alternative to traditional DPAK or D2PAK devices in server power supplies, power tools, and automotive electrical systems, especially suitable for designs requiring high power density and high reliability.
