CS6N80FA9R-VB Product details
Back to previous pageProduct introduction：
Imagine this: You are designing an industrial switching power supply or a photovoltaic inverter, with a system bus voltage as high as 800V, yet requiring the MOSFET to have stable high-voltage withstand capability and reliable heat dissipation performance. Ordinary low-voltage MOSFETs cannot handle this, while high-voltage devices often suffer from high conduction losses. VBsemi CS6N80FA9R-VB is created precisely for this purpose—it integrates 850V withstand voltage, 7A continuous current capability, and 1.7Ω on-resistance into a TO220F fully insulated package, allowing high-voltage power supply designs to find an ideal balance between safety, heat dissipation, and cost.
