Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tape-and-reel quantity and packaging format. Ensure that the HE3_A suffix correctly denotes AEC-Q101 qualification and RoHS compliance as specified by the manufacturer. Cross-reference the full part number with the latest Vishay datasheet revision to validate current production status and availability before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener solution with high precision is required in a small footprint. The ±2% tolerance makes it suitable for applications where standard commercial grade parts lack sufficient accuracy. Verify that the thermal dissipation requirements on the FR-4 board align with the 300 mW limit for surface mounting. Confirm that the operating voltage range falls within the specified Zener voltage window for optimal performance.

Part Context

This device belongs to the AZ23 series of small signal Zener diodes, which offers a wide range of voltages from 2.2 V to 75 V. The series is designed for general-purpose voltage regulation and protection tasks. The specific 'B' variant provides tighter tolerances compared to the standard 'C' grade, catering to more stringent design requirements while maintaining the same physical package dimensions and pinout compatibility.
