SQJ140ELP-T1_GE3-VB Product details
Back to previous pageProduct introduction：
The SQJ140ELP-T1_GE3-VB is a Single N-MOSFET deeply optimized for low-voltage, high-current power switching applications. Utilizing SGT (Split Gate Trench) technology, it combines ultra-low on-resistance with excellent switching characteristics. The LFPAK56 package achieves an excellent balance between high-current heat dissipation and compact board space. The combination of 40V voltage rating, 150A current capability, and 0.7mΩ on-resistance makes it an ideal choice for high-power applications such as server power supplies, power tools, and automotive DC-DC converters, especially for systems with stringent requirements for power density and thermal performance.
