Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the HE3 suffix indicates RoHS compliance and AEC-Q101 qualification. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to soldering.

Selection Notes

Select this component when a 10 V reference with tight tolerance is required in a compact SOT-23 footprint. Consider the positive temperature coefficient near 5 mV/°C for thermal stability requirements. Verify power dissipation limits against ambient temperature derating curves for high-temperature environments.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage options within the 2.2 V to 75 V range, all utilizing the same SOT-23 package format for consistent board layout strategies across different voltage requirements.

Replacement Considerations

Direct replacements must match the 10 V nominal voltage, SOT-23-3 package, and AEC-Q101 qualification. Verify equivalent dynamic resistance and leakage current specifications to ensure circuit performance parity.
