Procurement Notes
Verify the specific ordering code suffix against the manufacturer's official documentation to confirm tape-and-reel quantities and RoHS compliance status. Ensure that the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability throughout the supply chain.
Selection Notes
Select this component when a 24 V Zener voltage with ±5% tolerance is required in a compact SOT-23 footprint. The HE3_A suffix indicates AEC-Q101 qualification, making it suitable for automotive environments where standard commercial grade parts are insufficient. Verify thermal constraints against the 300 mW dissipation limit on the target PCB layout.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V, graded according to the E24 standard. The AZ23C24 variant specifically targets applications needing precise voltage regulation in space-constrained surface-mount designs.
