FDS4080N3
40V N-Channel FLMP PowerTrench MOSFET
General Description
Features
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 side” synchronous rectifier operation, providing an
extremely low RDS(ON) in a small package.
• 13 A, 40 V
RDS(ON) = 10.5 mΩ @ VGS = 10 V
• High performance trench technology for extremely
low RDS(ON)
• High power and current handling capability
Applications
•
•
• Fast switching (Qg = 30 nC )
Synchronous rectifier
DC/DC converter
• FLMP SO-8 package: Enhanced thermal
performance in industry-standard package size

Notes:
1. RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of
the drain pins. RθJC is guaranteed by design while RθCA is determined by the user's board design.
