PD -91623AAPPROVEDIRF3315HEXFET Power MOSFET Advanced Process TechnologyD Dynamic dv/dt RatingVDSS = 150V 175C Operating Temperature Fast SwitchingRDS(on) = 0.07 Fully Avalanche RatedGDescription ID = 27ASFifth 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 powerdissipation levels to approximately 50 watts. The lowthermal resistance and low package cost of the TO-TO-220AB220 contribute to its wide acceptance thr
