PD - 91406IRFZ48NHEXFET Power MOSFET Advanced Process TechnologyD Ultra Low On-ResistanceVDSS = 55V Dynamic dv/dt Rating 175C Operating TemperatureRDS(on) = 14m Fast SwitchingG Fully Avalanche RatedID = 64ASDescriptionAdvanced 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 contributeTO-220ABto its
