PD-93946A IRFP460P Dynamic dv/dt Rating HEXFET® Power MOSFET Repetitive Avalanche Rated D Isolated Central Mounting Hole VDSS = 500V Fast Switching Ease of Paralleling Simple Drive Requirements RDS(on) = 0.27? G Solder Plated for Reflowing ID = 20A Description S Third Generation HEXFET®s from International Rectifier provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness. The TO-247 package is preferred for commercial-industrial applications where higher power levels preclude the use of TO-220 devices. The TO-247 is similar but superior to the earlier TO-218 package because of its isolated mounting hole. It also provides greater creepage distance between pins to meet the requirement
