Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm tape width and reel quantity. Confirm that the HE3_A designation aligns with required AEC-Q101 qualification levels for your target application environment before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with high voltage accuracy is required in a small surface-mount footprint. Ensure the operating current remains within the specified test limits to maintain the ±2% tolerance. Verify thermal management requirements if ambient temperatures approach the upper operational limit.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers various voltage grades and tolerance options, including standard commercial grades and AEC-Q101 qualified versions. The B suffix indicates the tighter ±2% tolerance compared to the standard C grade.
