PD- 91705A IRF7322D1 FETKYTM MOSFET / Schottky Diode q q q q q q Co-packaged HEXFET(R) Power MOSFET and Schottky Diode Ideal For Buck Regulator Applications P-Channel HEXFET Low VF Schottky Rectifier Generation 5 Technology SO-8 Footprint A A S G 1 8 7 K K D D VDSS = -20V RDS(on) = 0.058 Schottky Vf = 0.39V 2 3 6 4 5 Top Vie w Description The FETKY family of co-packaged MOSFETs and Schottky diodes offers the designer an innovative, board space saving solution for switching regulator and power management applications. Generation 5 HEXFET Power MOSFETs utilize advanced processing techniques to achieve extremely low on-resistance per silicon area. Combinining this technology with International Rectifier's low forward drop Schottky rectifiers results in an extremely efficient device suitable for use in a wide variety of portable electronics applications. The SO-8 has been modified through a customized leadframe for enhanced thermal characteristics. The SO-8 package is designed for vapor phase, infrared or wave soldering techniques.
