MMSZ4689
5.1 V, 0.5 W Zener Diode
Features
General Description
• Compact Surface Mount with Same Footprint
as Mini-Melf
• 500 mW Rating on FR-4 or FR-5 Board.
• Class 3 ESD Rating (>16 kV) per Human Body Model
Half watt, general purpose, medium current surface
mount zener in the SOD-123 package. The SOD-123
package has the same footprint as the glass mini-melf
(LL-34) package and provides a convenient alternative to
the leadless package.

Absolute Maximum Ratings(1)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.

Notes
1. These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
2. Voltage change is equal to the difference between VZ at 100 μA and VZ at 10 μA.

AUTHORIZED USE
Unless otherwise specified in this data sheet, this product is a standard commercial product and is not intended for use in applications that require extraordinary
levels of quality and reliability. This product may not be used in the following applications, unless specifically approved in writing by a Fairchild officer: (1) automotive
or other transportation, (2) military/aerospace, (3) any safety critical application – including life critical medical equipment – where the failure of the Fairchild product
reasonably would be expected to result in personal injury, death or property damage. Customer’s use of this product is subject to agreement of this Authorized Use
policy. In the event of an unauthorized use of Fairchild’s product, Fairchild accepts no liability in the event of product failure. In other respects, this product shall be
subject to Fairchild’s Worldwide Terms and Conditions of Sale, unless a separate agreement has been signed by both Parties.
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.
Fairchild will not provide any warranty 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 buying direct or from authorized distributors.
