Procurement Notes

Verify authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit components pose significant risks; unauthorized sources do not provide warranty coverage. Confirm the part number includes the HE3 suffix for Halogen-free compliance and TP suffix for Tape & Reel packaging containing 3000 pieces per reel before finalizing orders.

Selection Notes

Select this component when a dual Zener solution with precise voltage matching is required in a small SOT-23 footprint. Ensure the operating current aligns with the 5.0 mA test condition for optimal voltage accuracy. Consider the 300 mW power dissipation limit and thermal resistance of 417°C/W when designing for elevated ambient temperatures or limited board space.

Part Context

This part belongs to the DZ23C series, which covers Zener voltages from 2.4 V to 47 V in the SOT-23 package. The series is designed for automated insertion and offers a wide operating temperature range suitable for demanding environments. The HE3 designation indicates the use of Green Planet Technology, ensuring environmental compliance alongside electrical performance.

Replacement Considerations

Direct substitutes within the same family include other DZ23C variants such as DZ23C10HE3-TP or DZ23C12HE3-TP if different voltage levels are acceptable. Cross-brand replacements must match the SOT-23-3 package, 300 mW power rating, and AEC-Q101 qualification status to ensure mechanical and electrical compatibility.
