hexfet ? power mosfet pd -91703 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 so-8 has been modified through a customized leadframe for enhanced thermal characteristics and multiple-die capability making it ideal in a variety of power applications. with these improvements, multiple devices can be used in an application with dramatically reduced board space. the package is designed for vapor phase, infra red, or wave soldering techniques. power dissipation of greater than 0.8w is possible in a typical pcb mount application. 02/24/99 description l generation v technology l ultra low on-resistance l dual n-channel mosfet l surface mount l available in tape & reel l dynamic dv/dt rating l fast switching so-8 v dss = 55v r ds(on) = 0.050 w IRF7341 www.irf.com 1 parameter max. units v ds drain- source voltage 55 v i d @ t c = 25c continuous drain current, v gs @ 10v 4.7 i d @ t c = 70c continuous drain current, v gs @ 10v 3.8 a i dm pulsed drain current ? 38 p d @t c = 25c power dissipation 2.0 p d @t c = 70c power dissipation 1.3 linear derating factor 0.016 w/c v gs gate-to-source voltage 20 v v gsm gate-to-source voltage single pulse tp<10s 30 v e as single pulse avalanche energy ? 72 dv/dt peak diode recovery dv/dt ? 5.0 v/ns t j, t stg junction and storage temperature range -55 to + 150 c parameter typ. max. units r q ja maximum junction-to-ambient ?
