Dual N-Channel 2.5V Specified PowerTrench
TM
MOSFET
General Description
These N-Channel low threshold 2.5V specified
MOSFETs are produced using Fairchild Semiconductor's
advanced PowerTrench process that has been
especially tailored to minimize on-state resistance and
yet maintain low gate charge for superior switching
performance.
Applications
Load switch
DC/DC converter
Motor driving

Notes:
1. R
JA
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
JC
is guaranteed by design while R
CA
is determined by the user's board design. Both devices are assumed to be operating and
sharing the dissipated heat energy equally.

Packaging Description:
SSOT-6 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
3,000 units per 7" or 177cm diameter reel. The reels are
dark blue in color and is made of polystyrene plastic (anti-
static coated). Other option comes in 10,000 units per 13"
or 330cm diameter reel. This and some other options are
described in the Packaging Information table.
These full reels are individually barcode labeled and
placed inside a pizza box (illustrated in figure 1.0) made of
recyclable corrugated brown paper with a Fairchild logo
printing. One pizza box contains three reels maximum.
And these pizza boxes are placed inside a barcode
labeled shipping box which comes in different sizes
depending on the number of parts shipped.
