Single N-Channel Enhancement Mode Field Effect Transistor

General Description Features

January 1998

SO-8 N-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

10.5 A, 20 V. R
R

High density cell design for extremely low R

High power and current handling capability in a widely used
surface mount package.

applications such as notebook computer power
management and other battery powered circuits where
fast switching, low in-line power loss, and resistance to

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
