Zener Voltage Regulators
225 mW SOT−23 Surface Mount
This series of Zener diodes is of fered in the convenient, surface
mount plastic SOT−23 package. These devices are designed to provide
voltage regulation with minimum space requirement. They are well
suited for applications such as cellular phones, hand held portables,
and high density PC boards.
Features
• 225 mW Rating on FR−4 or FR−5 Board
• Zener Voltage Range − 2.4 V to 91 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
• Peak Power − 225 W (8 x 20 ms)
• AEC−Q101 Qualified and PPAP Capable
• SZ Prefix for Automotive and Other Applications Requiring Unique
Site and Control Change Requirements
• Pb−Free Packages are Available

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
