FDD8586/FDU8586
N-Channel PowerTrench® MOSFET
20V, 35A, 5.5mΩ
Features
General Description
tm
Max rDS(on) = 5.5mΩ at VGS = 10V, ID = 35A
Max rDS(on) = 8.5mΩ at VGS = 4.5V, ID = 33A
Low gate charge: Qg(TOT) = 34nC(Typ), VGS = 10V
Low gate resistance
100% Avalanche tested
RoHS compliant
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
