FDD8878 Datasheet N-channel MOSFET

Manufacturer: Fairchild (now onsemi)

Overview: FDD8878 / FDU8878 N-Channel PowerTrench® MOSFET March 2015 FDD8878 / FDU8878 N-Channel PowerTrench® MOSFET 30V, 40A,.

General Description

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.
