Document Number: A, 28-Jul-081 Power MOSFETIRFP460, SiHFP460 Vishay SiliconixFEATURES Dynamic dV/dt Rating Repetitive Avalanche Rated Isolated Central Mounting Hole Fast Switching Ease of Paralleling Simple Drive Requirements Lead (Pb)-free AvailableDESCRIPTIONT hird generation Power MOSFETs from Vishay provide thedesigner with the best combination of fast switching,ruggedized device design, low on-resistance andcost-effectiveness. The TO-247 package is preferred for commercial-industrialapplications where higher Power levels preclude the use ofTO-220 devices. The TO-247 is similar but superior to theearlier TO-218 package because its isolated mounting also provides greater creepage distances between pins tomeet the requirements of most safety Repetitive rating; pulse width limited by maximum junction temperature (see fig.)
