Zener Voltage Regulator - ON Semiconductor
Description
MMSZxxxT1G Series, SZMMSZxxxT1G Series
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 • 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*
