3 Watt Plastic Surface Mount Zener Voltage Regulators
1SMB59xxBT3G Series, SZ1SMB59xxT3G Series
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*
Mechanical Characteristics: CASE: Void-free, transfer-molded plastic FINISH: All external surfaces are corrosion resistant and leads are
readily solderable MAXIMUM LEAD TEMPERATURE FOR SOLDERING PURPOSES:
260°C for 10 Seconds LEADS: Modified L−Bend providing more contact area to bond pads POLARITY: Cathode indicated by polarity band FLAMMABILITY RATING: UL 94 V−0
