General Description:
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.
Absolute Maximum Ratings (note 1) TA = 25
Features:
• 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
Ordering:
• 7 inch reel (178 mm); 8 mm Tape; 3,000 units per reel.

Packaging Description:
SOD123 parts are shipped in tape. The carrier tape is
made from a dissipative (carbon filled) polycarbonate
resin. The cover tape is a multilayer film (Heat Activated
Adhesive in nature) primarily composed of polyester film,
adhesive layer, sealant, and anti-static sprayed agent.
These reeled parts in standard option are shipped with
3,000 uni ts p er 7 " or 17 7cm di amet er re el. The reels are
dark blue in color and is made of polystyrene plastic (antistatic coated). Other option comes in 10,000 units per 13"
or 330cm diam eter reel. T his a nd some othe r opti ons ar e
described in the Packaging Information table.
These full reels are individually barcode labeled and
placed inside a pizza box (illustr ated in figure 1.0) made o f
recyclable corrugated brown paper with a Fairchild logo
printi ng. One pizza box contain s three r eels maximu m.
And these pizza boxes are placed inside a barcode
labeled shipping box which comes in different sizes
depending on the num ber of parts s hipped.
