General Description
This P-Channel Logic Level MOSFET is produced using
Fairchild Semiconductors 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 are well suited for notebook computer appli-
cations: load switching and power management, battery
charging circuits, and DC/DC conversion.

is the sum of the junction-to-case and case-to-ambient resistance where the case thermal reference is defined as the solder mounting surface of the
drain pins. R
qJC
is guaranteed by design while R
qCA
is determined by the user's board design.
