Dual N & P-Channel Enhancement Mode Field Effect Transistor
General Description Features
July 1996
These dual N- and P -Channel enhancement mode power
field effect transistors are produced using Fairchild's
proprietary, high cell density, DMOS technology. This very high
density process is especially tailored to minimize on-state
resistance and provide superior switching performance. These
devices are particularly suited for low voltage applications such
as notebook computer power management and other battery
powered circuits where fast switching, low in-line power loss,
and resistance to transients are needed.

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 uni t s pe r 13" o r 33 0c m d ia met er reel . Th e reel s ar e
dark blue in color and is made of polystyrene plastic (antistatic coated). Other option comes in 500 units per 7" or
177cm di ameter reel. This and some o ther 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 di ff ere nt siz es depe nd in g on th e num be r of pa rts
