MOSFET
General Description
These N-Channel 2.5V specified MOSFETs are
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.

JA
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. R
JC
is guaranteed by design while R
CA
is determined by the user's board design.

Packaging Description:
SOIC-8 parts are shipped in tape. The carrier tape is
made from a dissipative (carbon filled) polycarbonate
resin. The cover tape is a multilayer film (Heat Activated
Adhesive in nature) primarily composed of polyester film,
adhesive layer, sealant, and anti-static sprayed agent.
These reeled parts in standard option are shipped with
2,500 units per 13" or 330cm diameter reel. The reels are
dark blue in color and is made of polystyrene plastic (anti-
static coated). Other option comes in 500 units per 7" or
177cm diameter reel. This and some other options are
further described in the Packaging Information table.
These full reels are individually barcode labeled and
placed inside a standard intermediate box (illustrated in
figure 1.0) made of recyclable corrugated brown paper.
One box contains two reels maximum. And these boxes
are placed inside a barcode labeled shipping box which
comes in different sizes depending on the number of parts
shipped.
