Single N-Channel Logic Level PWM Optimized PowerTrench
®
MOSFET
General Description
This N-Channel Logic Level MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers.
The MOSFET features faster switching and lower gate
charge than other MOSFETs with comparable R
DS(ON)
specifications.
The result is a MOSFET that is easy and safer to drive (even
at very high frequencies), and DC/DC power supply designs
with higher overall efficiency.

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.
