SZ1SMB59xxT3G Series
3 Watt Plastic
Surface Mount
Zener Voltage Regulators
This complete new line of 3 W Zener diodes offers the following
advantages.
Features
• Zener Voltage Range − 3.3 V to 200 V
• ESD Rating of Class 3 (> 16 kV) per Human Body Model
• Flat Handling Surface for Accurate Placement
• Package Design for Top Side or Bottom Circuit Board Mounting
• AEC−Q101 Qualified and PPAP Capable − SZ1SMB59xxT3G
• SZ Prefix for Automotive and Other Applications Requiring Unique
Site and Control Change Requirements
• These are Pb−Free Devices*
