FQI11N40TU-VB Product details
Back to previous pageProduct introduction：
You are designing a high-reliability industrial power supply that needs to handle wide input voltage and severe surge impacts while balancing efficiency and temperature rise. Ordinary high-voltage MOS tubes either have high conduction losses or insufficient avalanche capability. VBsemi FQI11N40TU-VB is designed for this—it integrates 650V withstand voltage, 12A continuous current-carrying capacity, and a low on-resistance of 360mΩ into a TO262 package, combined with SJ_Multi-EPI super junction technology, achieving an ideal balance between performance and cost for high-voltage switching applications.
