Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the HE3 suffix indicates RoHS compliance and AEC-Q101 qualification as specified in the datasheet. Ensure storage conditions adhere to moisture sensitivity level 1 requirements before soldering.
Selection Notes
Select this component when a 7.5 V reference with low leakage is required in a compact SOT-23 footprint. Consider the 5 mA test current and 7 Ω dynamic resistance for precision applications. Verify thermal management capabilities against the 300 mW dissipation limit on FR-4 boards.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, utilizing standardized E24 grading. The HE3 variant specifically denotes automotive-grade qualification alongside environmental compliance.
Replacement Considerations
Direct substitutes must match the 7.5 V Zener voltage, SOT-23 package, and AEC-Q101 qualification. Verify equivalent dynamic resistance and leakage current specifications to ensure circuit compatibility without redesign.
