Feature Summary

• Dual Zener diode array with common anode topology
• Surface-mount SOT-23 packaging for compact integration
• High thermal stability across extended temperature ranges

Applications

• Voltage reference circuits requiring stable dual rails
• Overvoltage protection stages in signal paths
• Clamping applications in low-power electronic systems

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to ensure compliance with lead-free requirements and tape-and-reel specifications. Confirm that the selected variant matches the required voltage tolerance and package dimensions for your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener solution with a common anode is required within a minimal footprint. Ensure the application voltage does not exceed the 33 V limit and that the 350 mW power rating accommodates the expected thermal load. Verify compatibility with standard SOT-23 footprints during the design phase.

Part Context

This part belongs to the CMPZDA series of dual Zener diodes produced by Central Semiconductor Corp. It is designed for general-purpose voltage regulation and protection tasks where space efficiency is critical. The series offers various voltage options within the same package family to simplify supply chain management.

Replacement Considerations

Direct substitutes must match the SOT-23 package, common anode configuration, and 33 V Zener voltage. Verify equivalent power ratings and leakage current specifications to ensure circuit performance remains unaffected during replacement.
