Procurement Notes
Verify the specific suffix HE3_A-08 against official Vishay documentation to confirm RoHS compliance and halogen-free status. Confirm availability as this component may be subject to production lifecycle changes. Ensure the ordering quantity aligns with standard reel packaging requirements specified by the manufacturer.
Selection Notes
Select this component when a dual common cathode Zener configuration is required in an SOT-23-3 footprint. The 68 V breakdown voltage and 300 mW power rating suit low-power regulation tasks. Verify that the 5% tolerance and 40 Ohm impedance meet the specific circuit accuracy and dynamic response requirements.
Part Context
This part belongs to the DZ23 series of dual Zener diodes from Vishay Semiconductors. The series offers various voltage options in a compact SOT-23-3 package. These devices are commonly used in portable electronics and automotive systems where board space is limited and reliable voltage referencing is critical.
Replacement Considerations
Check for direct substitutes within the DZ23 series or equivalent dual Zener diodes from other manufacturers. Ensure any replacement matches the SOT-23-3 package, 68 V Zener voltage, and 300 mW power dissipation. Verify AEC-Q101 qualification if automotive application is required.
