MMSZ5257B

5% TOLERANCE

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
