FDD8878 / FDU8878 N-Channel MOSFET

April 2008

FDD8878 / FDU8878

N-Channel MOSFET
30V, 40A,
rDS ON = VGS = 10V, ID = 35A rDS ON = VGS = 4.5V, ID = 35A High performance trench technology for extremely low

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.
rDS ON

Low gate charge High power and current handling capability

Application
- DC / DC Converters
