FQPF9N50YDTU-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-efficiency switching power supply but facing the challenges of high-voltage breakdown, conduction loss, and heat dissipation? Ordinary high-voltage MOS tubes either lack sufficient voltage tolerance or have high on-resistance, causing the overall temperature to remain high. The VBsemi FQPF9N50YDTU-VB is designed for this—it is based on SJ_Multi-EPI super-junction technology, achieving 500V voltage tolerance, 7A continuous current, and a low on-resistance of 550mΩ in a TO220F package, providing solid support for industrial-grade power supplies and high-reliability applications.
