IRF840LCL-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-voltage industrial power supply or motor drive system that needs to withstand a 650V bus voltage while balancing conduction losses and heat dissipation costs? Ordinary MOSFETs either lack sufficient voltage resistance or have high on-resistance. VBsemi IRF840LCL-VB is designed for this—it uses SJ_Multi-EPI super junction technology to integrate 650V voltage resistance, 12A current-carrying capacity, and 360mΩ on-resistance into a TO262 package, providing a solid and reliable switching solution for high-voltage, high-power applications.
