MMSZ4702 MMSZ4702 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 (LL34) 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=25C unless otherwise noted Symbol TSTG Storage Temperature Parameter Value -55 ~ 150 Units C TJ Maximum Junction Temperature -55 ~ 150 C PD Total Power Dissipation at 25C Derate above 25C 500 6.7 mW mW/C RQJA Thermal Resistance Junction to Ambient 340 C/W RQJL Thermal Resistance Junction to Lead 150 C/W VZ Maximum Voltage Change (Note 2) 150 mV Lead Solder Temperature (Max 10 second duration) 260 C Nominal Zener Voltage (VZ) at 50A 15.0 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 100A and VZ at 10A.
