FDB8878 N-Channel MOSFET

November 2005

FDB8878 N-Channel Logic Level MOSFET
30V, 48A,

General Descriptions

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 = VGS = 10V, ID = 40A - rDS ON = VGS = 4.5V, ID = 36A - High performance trench technology for extremely low
rDS ON - Low gate charge
- High power and current handling capability
- RoHS Compliant
