Procurement Notes
Verify the specific suffix HE3_A-08 against official Vishay documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure the component meets RoHS directives and REACH requirements for your target market before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution is required in a compact SOT-23-3 footprint. The 75 V breakdown voltage suits higher voltage reference needs compared to lower voltage variants in the DZ23 series. Confirm that the 300 mW power rating aligns with the thermal management capabilities of the target PCB layout.
Part Context
This part belongs to the Vishay DZ23 series of dual Zener diodes. The series offers various voltage options in a standardized surface-mount package. The HE3 designation indicates a high-efficiency planar die structure designed for improved performance and reliability over standard equivalents.
Replacement Considerations
Check Vishay's official cross-reference guides for direct replacements. Verify pinout compatibility and electrical parameters such as Zener impedance and leakage current when considering alternative manufacturers' dual Zener diodes in SOT-23 packages.
