PD - 94787IRFZ44NPbFHEXFET Power MOSFET Advanced Process Technology Ultra Low On-ResistanceD Dynamic dv/dt RatingVDSS = 55V 175C Operating Temperature Fast SwitchingRDS(on) = 17.5m Fully Avalanche RatedG Lead-FreeID = 49ASDescriptionAdvanced HEXFET Power MOSFETs from InternationalRectifier utilize advanced processing techniques to achieveextremely low on-resistance per silicon area. This benefit,combined with the fast switching speed and ruggedizeddevice design that HEXFET power MOSFETs are wellknown for, provides the designer with an extremely efficientand reliable device for use in a wide variety of applications.The TO-220 package is universally preferred for allcommercial-industrial applications at power dissipationlevels to approximately 50 watts. The low thermalresistance and low package cost of the TO-220 contribute
