FAIRCHILD FDR6678A

FDR6678A
30V N-Channel PowerTrench MOSFET
General Description
Features
This N-Channel MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers. It has been optimized for
“high side” synchronous rectifier operation, providing an
extremely low RDS(ON) and fast switching in a small
package.
• 7.5 A, 30 V.
RDS(ON) = 24 mΩ @ VGS = 4.5V
RDS(ON) = 20 mΩ @ VGS = 10 V
• High performance trench technology for extremely
low RDS(ON)
• Fast switching, low gate charge
Applications
• High power and current in a smaller footprint than
SO-8
• DC/DC converter

Anti static Cover Tape
SSOT-8 parts are shipped in tape. The carrier tape is
made from a di ssipat ive (carbo n filled) po ly carbon ate
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 w ith
3,000 units per 13" or 330cm diameter reel. The reels are
dark blue in color and is made of polystyrene plastic (antistatic coated). Other option comes in 500 unit s per 7" or
177cm diameter reel. This and some other options are
further described in the Packagin g Information table.
These full reels are in di vidu ally barcod e labeled and
placed inside a standard intermediate box (ill ustrated in
figure 1.0) made of recyclable corrugated brow n paper.
One box contains two reels maximum. And t hese boxes
