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
• 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.
Absolute Maximum Ratings (note 1) TA = 25^OC unless otherwise noted
