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.
Features
• 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.
