PD - 9.1280C IRF4905 HEXFET Power MOSFET Advanced Process Technology D Ultra Low On-Resistance VDSS = -55V Dynamic dv/dt Rating 175 C Operating Temperature RDS(on) = 0.02 Fast Switching G P-Channel ID = -74A Fully Avalanche Rated S Description Fifth Generation HEXFETs from International Rectifier utilize advanced processing techniques to achieve extremely low on-resistance per silicon area. This benefit, combined with the fast switching speed and ruggedized device design that HEXFET Power MOSFETs are well known for, provides the designer with an extremely efficient and reliable device for use in a wide variety of applications. The TO-220 package is universally preferred for all commercial-industrial applications at power dissipation levels to approximately 50 watts. The low thermal TO-220AB resistance and low package cost of the TO-220 contri
