SQJ420EP-T1_GE3-VB Product details
Back to previous pageProduct introduction：
SQJ420EP-T1_GE3-VB is a Single N-MOS deeply optimized for low-voltage high-power switching scenarios. Trench technology balances extremely low conduction losses with high switching reliability, and the LFPAK56 package achieves an excellent balance between thermal capability and footprint. The combination of 40V withstand voltage, 100A current-carrying capacity, and 2mΩ-class on-resistance makes it an ideal high-performance alternative to traditional DPAK, D2PAK, or SOP-8 package devices, especially for applications requiring high power density and continuous high-current output.
