FCH067N65S3-VB Product details
Back to previous pageProduct introduction：
** Are you designing a high-power-density server power supply or photovoltaic inverter, needing to withstand 650V while maintaining extremely low losses at high currents? Ordinary high-voltage MOSFETs either have high on-resistance or high switching losses, making thermal design a nightmare. The VBsemi FCH067N65S3-VB is designed for this – it utilizes SJ_Multi-EPI super-junction technology to integrate a 650V voltage rating, 47A current capability, and an ultra-low on-resistance of just 50mΩ into the robust TO247 package, providing a powerful and reliable power switching solution for high-end industrial power supplies.**
