automotive grade features advanced planar technology low on-resistance dual n and p channel mosfet dynamic dv/dt rating 150c operating temperature fast switching lead-free, rohs compliant automotive qualified* description specifically designed for automotive applications, this cellular design of hexfet? power mosfets utilizes the latest processing techniques to achieve low on-resistance per silicon area. this benefit com- bined 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 automotive and a wide variety of other applications. so-8 AUIRF7309Q absolute maximum ratings stresses beyond those listed under ?absolute maximum ratings? may cause permanent damage to the device. these are stress rati ngs only; and functional operation of the device at these or any other condition beyond those indicated in the specifications is no t implied. exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. the thermal resistance and power dissi pation ratings are measured under board mounted and still air conditions. ambient temperature (t a ) is 25c, unless otherwise specified. hexfet ? is a registered trademark of international rectifier. * qualification standards can be found at http://www.irf.com/ n-ch p-ch v (br)dss 30v -30v r ds(on) max. 0.05 0.10 i d 4.7a -3.5a d1 d1 d2 d2 g1 s2 g2 s1 top view 8 1 2 3 4 5 6 7 p-channel mosfet n-channe l mos fe t parameter units n-channel p-channel i d @ t a = 25c 10 sec. pulsed drain current, v gs @ 10v 4.7 -3.5 i d @ t a = 25c continuous drain current, v gs @ 10v 4-3.0 i d @ t a = 70c continuous drain current, v gs @ 10v 3.2 -2.4 i dm pulsed drain current 16 -12 p d @t a = 25c power dissipation linear derating factor w/c v gs gate-to-source voltage v dv/dt peak diode recovery dv/dt 6.9 -6.0 v/ns t j operating junction and t stg storage temperature range thermal resistance parameter typ. max. units r ja junction-to-ambient (pcb mount, steady state) ??? 90 c/w -55 to + 150 max. 1.4 0.011 20 w a c
