FDMS7578
N-Channel Power Trench® MOSFET
25 V, 5.8 mΩ
Features
General Description
Max rDS(on) = 5.8 mΩ at VGS = 10 V, ID = 17 A
Max rDS(on) = 8 mΩ at VGS = 4.5 V, ID = 14 A
Advanced Package and Silicon combination for low rDS(on)
and high efficiency
Next generation enhanced body diode technology, engineered
for soft recovery
MSL1 robust package design
This N-Channel MOSFET has been designed specifically to
improve the overall efficiency and to minimize switch node
ringing of DC/DC converters using either synchronous or
conventional switching PWM controllers. It has been optimized
for low gate charge, low rDS(on), fast switching speed and body
diode reverse recovery performance.
Applications
Control MOSFET for Synchronous Buck Converters
100% UIL tested
Notebook
RoHS Compliant
Server
Telecomm
High Efficiency DC-DC Switch Mode Power Supplies
