Procurement Notes

Verify the specific suffix WHE3 against official manufacturer documentation to confirm compliance details and pinout compatibility. Ensure that the sourcing channel provides valid traceability records. Cross-reference the part number with the latest datasheet to confirm active status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener array with a 16 V breakdown is required in an SOT-23-3 footprint. Confirm that the 300 mW power rating meets the thermal requirements of the target application. Verify that the 40 Ohm impedance and 100 nA leakage characteristics align with the precision needs of the circuit design.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from Micro Commercial Components. It shares the SOT-23-3 package form factor with other variants in the family but differs in Zener voltage ratings and specific electrical parameters. The HE3 suffix typically indicates specific halogen-free or environmental compliance attributes defined by the manufacturer.

Replacement Considerations

Direct substitutes must match the SOT-23-3 package, 16 V Zener voltage, and dual common anode configuration. Verify equivalent power dissipation and impedance values. Check for identical pinout assignments to ensure physical compatibility without PCB redesign.
