Zener Diode

MMSZ4703 — Zener Diode

July 2009

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.
