FCH170N60-VB Product details
Back to previous pageProduct introduction：
FCH170N60-VB is a Single N-MOS deeply optimized for high-voltage power switching scenarios. It uses SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology to achieve an excellent balance between low on-resistance and low switching losses at a 600V voltage rating. The TO247 package offers excellent heat dissipation and creepage distance, making it suitable for high-power, high-reliability industrial and energy system applications. The combination of 25A continuous current-carrying capacity and 120mΩ on-resistance makes it a cost-effective alternative to traditional planar MOSFETs in topologies such as high-voltage rectification, inversion, and PFC, especially suitable for projects with strict requirements on temperature rise and efficiency.
