FDD8782/FDU8782 N-Channel MOSFET

March 2015

FDD8782/FDU8782 N-Channel MOSFET
25V, 35A, 11mΩ

This N-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. It has been optimized for low gate charge, low rDS on and fast switching speed.

Application
- Vcore DC-DC for Desktop Computers and Servers - VRM for Intermediate Bus Architecture
- Max rDS on = 11.0mΩ at VGS = 10V, ID = 35A - Max rDS on = 14.0mΩ at VGS = 4.5V, ID = 35A - Low gate charge Qg 10 = 18nC Typ , VGS = 10V - Low gate resistance - Avalanche rated and 100% tested - RoHS Compliant
