irf4905pbf hexfet ? power mosfet pd - 94816 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 resistance and low package cost of the to- 220 contribute to its wide acceptance throughout the industry. parameter max. units i d @ t c = 25c continuous drain current, v gs @ -10v -74 i d @ t c = 100c continuous drain current, v gs @ -10v -52 a i dm pulsed drain current -260 p d @t c = 25c power dissipation 200 w linear derating factor 1.3 w/c v gs gate-to-source voltage 20 v e as single pulse avalanche energy 930 mj i ar avalanche current -38 a e ar repetitive avalanche energy 20 mj dv/dt peak diode recovery dv/dt -5.0 v/ns t j operating junction and -55 to + 175 t stg storage temperature range soldering temperature, for 10 seconds 300 (1.6mm from case ) c mounting torque, 6-32 or m3 screw 10 lbf?in (1.1n?m) absolute maximum ratings parameter typ. max. units r jc junction-to-case ??? 0.75 r cs case-to-sink, flat, greased surface 0.50 ??? c/w r ja junction-to-ambient ??? 62 thermal resistance v dss = -55v r ds(on) = 0.02 ? i d = -74a t o -22 0 ab advanced process technology ultra low on-resistance dynamic dv/dt rating 175c operating temperature fast switching p-channel fully avalanche rated lead-free description 11/6/03 s d g
