600 V CoolMOS™ S7 in QDPAK and TO-220 package

The 600V 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 top side cooling minimizes conduction losses and maximizes power density, with the most efficient SMD cooling.
