Three complete series of Zener Diodes are offered in the convenient, surface mount
plastic SOD-123 package. These devices provide a convenient alternative to the leadless
34 package style.
500 mW Rating on FR-4 or FR-5 Board
Package Designed for Optimal Automated Board Assembly
Corrosion Resistant Finish, Easily Solderable
ESD Rating of Class 3 (exceeding 16 kV) per the Human Body Model
Small Package Size for High Density Applications
Available in 8 mm Tape and Reel
Add “T1” to the device number to order the 7 inch / 3000 unit reel.
Add “T3” to the device number to order the 13 inch / 10,000 unit reel.
