Description
The
FETKY™
family of Co-Pack HEXFET
®
Power 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.
