PD - 91318BIRFR/U1205HEXFET Power MOSFET Ultra Low On-ResistanceD Surface Mount (IRFR1205)VDSS = 55V Straight Lead (IRFU1205) Fast SwitchingRDS(on) = 0.027 Fully Avalanche RatedGDescriptionID = 44A SFifth Generation HEXFETs from International Rectifierutilize advanced processing techniques to achieve thelowest possible 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 device for use in a widevariety of applications.The D-PAK is designed for surface mounting usingvapor phase, infrared, or wave soldering techniques. D -P AK I-PA KThe straight lead version (IRFU series) is for through-T O-252AA TO-251AAhole mounting applications. Power dissipation levelsup to 1.5 watts are
