MMSZ4684

General Description Features Half watt, General purpose, Medium Current Surface Compact surface mount with same footprint as mini-melf Mount Zener in the SOD-123 package. The SOD-123 500m W rating on FR-4 or FR-5 board. package has the same footprint as the glass mini-melf (LL- Class 3 ESD rating (>16k V) per Human Body Model 34) package & provides a convenient alternative to the Leadless package.

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 ~ 150 °C

TJ Maximum Junction Temperature -55 ~ 150 °C PD Total Power Dissipation at 25°C m W Derate above 25°C 6.7 m W/°C

RQJA Thermal Resistance Junction to Ambient °C/W

RQJL Thermal Resistance Junction to Lead °C/W

∆VZ Maximum Voltage Change (note 2) m V Lead Solder Temperature (Max 10 second duration) °C

Nominal Zener Voltage (VZ) at 50µA 3.3

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.
