Fairchild FDS2070N3 150v n-channel powertrench mosfet Datasheet

FDS2070N3
150V N-Channel 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.
• 4.1 A, 150 V. RDS(ON) = 78 mΩ @ VGS = 10 V
Applications
• High power and current handling capability
• Synchronous rectifier
• Fast switching, low gate charge (38nC typical)
RDS(ON) = 88 mΩ @ VGS = 6.0 V
• High performance trench technology for extremely
low RDS(ON)
• 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.
