MMSZ4703 Zener Diode General Description Features 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 & provides a convenient alternative to the leadless package. • Compact surface mount with same footprint as mini-melf • 500mW rating on FR-4 or FR-5 board. • Class 3 ESD rating (>16kV) per Human Body Model Ordering • 7 inch reel (178mm); 8mm Tape; 3,000 units per reel. Absolute Maximum Ratings (note 1) TA=25°C unless otherwise noted Symbol Parameter Value Units TSTG Storage Temperature -55 to +150 °C TJ Maximum Junction Temperature -55 to +150 °C PD Total Power Dissipation at 25°C Derate above 25°C 500 6.7 mW mW/°C RQJA Thermal Resistance Junction to Ambient 340 °C/W RQJL Thermal Resistance Junction to Lead 150 °C/W ΔVZ Maximum Voltage Change (Note 2) 160 mV Lead Solder Temperature (Max 10 second duration) 260 °C Nominal Zener Voltage (VZ) at 50μA 16.0 V Note 1: These ratings are limiting values above which the serviceability of any semiconductor device may be impaired. Note 2: Voltage change is equal to the difference between VZ at 100μA and VZ at 10μA.

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 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 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.
