Zener Voltage Regulators
500 mW SOD−123 Surface Mount
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.
Features
• 500 mW Rating on FR−4 or FR−5 Board
• Wide Zener Reverse Voltage Range − 2.4 V to 56 V
• Package Designed for Optimal Automated Board Assembly
• Small Package Size for High Density Applications
• ESD Rating of Class 3 (>16 kV) per Human Body Model
• We declare that the material of product
compliance with RoHS requirements.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
