950 V CoolMOS™ PFD7 superjunction MOSFET in TO-252 DPAK package The PFD7 is tailored to ultrahigh power density as well as the highest efficiency designs. The products primarily address consumer and industrial SMPS applications for PFC and LLC/LCC topologies. The 950 V CoolMOS™ PFD7 combines a 60% Qg reduction over CoolMOS™ C3 (resulting in the reduction of driving losses and improved light and full load efficiency) with a fast and robust body diode.
