N-Channel, PowerT rench MOSFET
FDD5680
July 2000
General Description
This N-Channel MOSFET is produced using Fairchild
Semiconductor's advanced PowerTrench process that has
been especially tailored to minimize the on-state
resistance and yet maintain low gate charge for superior
switching performance.
