IRF4905S/l hexfet ? power mosfet pd - 9.1478a l advanced process technology l surface mount (IRF4905S) l low-profile through-hole (irf4905l) l 175c operating temperature l fast switching l p-channel l fully avalanche rated 8/25/97 s d g absolute maximum ratings 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 d 2 pak is a surface mount power package capable of accommodating die sizes up to hex-4. it provides the highest power capability and the lowest possible on- resistance in any existing surface mount package. the d 2 pak is suitable for high current applications because of its low internal connection resistance and can dissipate up to 2.0w in a typical surface mount application. the through-hole version (irf4905l) is available for low- profile applications. description v dss = -55v r ds(on) = 0.02 w i d = -74a 2 d pak to-262 parameter typ. max. units r q jc junction-to-case CCC 0.75 r q ja junction-to-ambient ( pcb mounted,steady-state)** CCC 40 thermal resistance c/w 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 a = 25c power dissipation 3.8 w 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
