Infineon's 600 V SJ MOSFET in bottom-side cooled package minimizes conduction losses and enables standardized cooling and mounting of the device The 600 V CoolMOS™ S7 SJ MOSFET family is optimized for low conduction losses and features the lowest RDS(on) in the market when it comes to high-voltage SJ MOSFETs in a compact SMD package. It comes with an unprecedented RDS(on) x price figure of merit and is a perfect fit for solid-state circuit breakers and relays, PLCs, battery protection, and active bridge rectification in high-power power supplies. The bottom-side cooled package minimizes conduction losses and enables standardized cooling and mounting of the device.
