Zener Voltage Regulators
500 mW SOD−123 Surface Mount
MMSZ52xxxT1G Series, SZMMSZ52xxxT1G Series
SOD−123 CASE 425 STYLE 1
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
