FDS8449
40V N-Channel PowerTrench^® MOSFET
General Description
These N-Channel MOSFETs are produced using
Fairchild Semiconductor’s advanced PowerTrench
process that has been especially tailored to minimize
on-state resistance and yet maintain superior switching
performance.
Application
• Inverter
• Power Supplies
Features
• 7.6 A, 40V R_DS(on) = 29mΩ @ V_GS = 10V
R_DS(on) = 36mΩ @ V_GS = 4.5V
• High power handling capability in a widely used
surface mount package
• RoHS compliant
