PD - 91504AIRF1310NHEXFET Power MOSFET Advanced Process TechnologyD Dynamic dv/dt RatingVDSS = 100V 175C Operating Temperature Fast SwitchingRDS(on) = 0.036 Fully Avalanche RatedGDescription ID = 42ASFifth Generation HEXFETs from International Rectifierutilize advanced processing techniques to achieveextremely low on-resistance per silicon area. Thisbenefit, combined with the fast switching speed andruggedized device design that HEXFET PowerMOSFETs are well known for, provides the designerwith an extremely efficient and reliable device for usein 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-220TO-220ABcontribute to its wide acceptance throughout
