FDD8796/FDU8796
N-Channel PowerTrench® MOSFET
25V, 35A, 5.7mΩ
AD FREE I
General Description
Features
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.
Max rDS(on) = 5.7mΩ at VGS = 10V, ID = 35A
Max rDS(on) = 8.0mΩ at VGS = 4.5V, ID = 35A
Low gate charge: Qg(10) = 37nC(Typ), VGS = 10V
Low gate resistance
Application
Avalanche rated and 100% tested
Vcore DC-DC for Desktop Computers and Servers
RoHS Compliant
VRM for Intermediate Bus Architecture
