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.
SO-8
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.
