Small Signal Diode
Absolute Maximum Ratings * TA = 25°C unless otherwise noted
* These ratings are limiting value s ab ove which the serviceability of the diode ma y be impaired.
NOTES:
1)These ratings are based on a maximum junction temperature of 150 degrees C.
2) These are steady limits. The factory should be consulted on applications involving pulsed or low duty cycle
operations.

LIFE SUPPORT POLICY
FAIRCHI LD’S PRODUCTS ARE NOT AUTHORIZED F OR USE AS CRITI CAL COM PONENTS IN LI FE SUPPORT DEVICES OR SY STEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAI RCHI LD SEM ICONDUCTOR CO RPORATION.
As used herein:
1. Life support devices or systems are devices or systems which, (a) are

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, w ww.fairchildsemi.com,
under Sales Support.
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 delay s. 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 w arranties and will appropriately address any warranty issues t hat may arise. Fairch ild will not p rovide
any w arranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buy ing direct or from authorized distributors.
