Procurement Notes

Verify the specific suffix HE3 against official datasheets to confirm halogen-free status and RoHS compliance. Confirm the manufacturer part number AZ23C20WHE3-TP matches the required electrical parameters before procurement. Ensure the ordering quantity aligns with standard factory packaging limits to avoid partial reel issues.

Selection Notes

Select this component when a dual Zener solution is required in a minimal footprint. The 20 V breakdown voltage suits mid-range reference applications. Verify that the 300 mW power rating meets the thermal requirements of the target environment. The SOT-23 package is suitable for automated surface-mount assembly processes.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from Micro Commercial Components. The series offers various voltage options in a standardized SOT-23 package. The HE3 suffix typically denotes halogen-free construction compliant with environmental directives. This family targets automotive and industrial sectors requiring robust discrete semiconductor solutions.

Replacement Considerations

Cross-reference with other AZ23C20 variants from MCC or equivalent dual Zener arrays from other manufacturers. Ensure pinout compatibility and identical voltage tolerance specifications. Verify that substitute components meet the same AEC-Q101 automotive qualification if used in regulated environments.
