• Clamping applications in signal processing

Procurement Notes

Verify the specific ordering code suffix to confirm reel dimensions and minimum order quantities. Confirm that the component meets the required environmental compliance standards for the target assembly process. Ensure the selected variant matches the necessary thermal management requirements for the final enclosure design.

Selection Notes

Select this component when a precise 3.6 V reference is needed in a compact footprint. Evaluate the dynamic resistance and leakage current specifications against circuit sensitivity requirements. Consider the thermal derating curves if the application involves elevated ambient temperatures or continuous power dissipation near the maximum rating.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series covers a wide voltage range from 2.2 V to 75 V, all utilizing the same SOT-23 package format. This specific model represents one of the lower voltage options within the lineup, optimized for low-voltage logic protection tasks.

Replacement Considerations

Direct replacements include other DZ23 series variants with identical packaging but different voltage ratings, such as DZ23C3V3-E3-18 or DZ23C3V9-E3-18. Cross-manufacturer equivalents must be verified for pinout compatibility and electrical parameter alignment.
