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. Zener voltage

in this series are specified with device junction in thermal equilibrium.

Features

• 500 mW Rating on FR−4 or FR−5 Board

• Wide Zener Reverse Voltage Range − 2.4 V to 110 V @ Thermal

Equilibrium*

• Package Designed for Optimal Automated Board Assembly

• Small Package Size for High Density Applications

• General Purpose, Medium Current

• ESD Rating of Class 3 (> 16 kV) per Human Body Model

• SZ Prefix for Automotive and Other Applications Requiring Unique

Site and Control Change Requirements; AEC−Q101 Qualified and

PPAP Capable

• These are Pb−Free Devices*

Mechanical Characteristics:

Stresses exceeding those listed in the Maximum Ratings table may damage the

device. If any of these limits are exceeded, device functionality should not be

assumed, damage may occur and reliability may be affected.
