FETKY™ MOSFET / SCHOTTKY DIODE
• Co-Pack N-channel HEXFET
®
Power MOSFET
and Schottky Diode
• Ideal for Synchronous Rectifiers in DC-DC
Converters up to 5A Output
• Low Conduction Losses
• Low Switching Losses
• Low Vf Schottky Rectifier
Description
The FETKY
™
family of Co-Pack HEXFET
®
MOSFETs
and Schottky diodes offers the designer an innovative,
board space saving solution for switching regulator and
power management applications. HEXFET power
MOSFETs utilize advanced processing techniques to
achieve extremely low on-resistance per silicon area.
Combining 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.
