General Description
This N-Channel 2.5V specified 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.
These devices have been designed to offer exceptional power
dissipation in a very small footprint compared with bigger SO-8
and TSSOP-8 packages.
