PD-94011A SMPS MOSFET IRFP460AS HEXFET® Power MOSFET Applications SMPS, UPS, Welding and High Speed VDSS Rds(on) max ID Power Switching 500V 0.27? 20A Benefits Dynamic dv/dt Rating Repetitive Avalanche Rated Isolated Central Mounting Hole Fast Switching Ease of Paralleling Simple Drive Requirements Solder plated and leadformed for surface mounting Description Third Generation HEXFET®s from International Rectifier provide the designer with the best combination of fast switching, ruggedized SMD-247 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
