Description
The FFB20UP20DN_F085 is an ultrafast rectifier. It has
a low
forward voltage drop and is a silicon nitride passivated
ion-implanted
epitaxial planar construction.
This device is intended for use as a freewheeling/clamping
rectifier in a variety of switching power supplies and other
power switching applications. Its low stored charge and
hyperfast recovery minimize ringing and electrical noise in
many power switching circuits, thus reducing power loss in
the switching transistors.
Applications
Output Rectifiers
Switching Mode Power Supply
Free-wheeling diode for motor application
Power switching circuits
Qualified to AEC Q101
RoHS Compliant

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,
under Terms of Use
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed
applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild
Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors
are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical
and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise.
