Procurement Notes

Verify the specific manufacturer datasheet for the AZ23B4V3HE3-TP to confirm all electrical parameters and mechanical dimensions before finalizing designs. Ensure that the ordering suffix matches the required packaging format, such as reel or cut tape, as availability may vary by distributor region. Cross-reference the part number with official Micro Commercial Components documentation to validate compliance and authenticity.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small footprint. The 4.3 V nominal voltage suits applications needing precise low-voltage references. Consider the 300 mW power dissipation limit and the 80 Ohm impedance value for accuracy requirements. The SOT-23-3 package is suitable for high-density PCB layouts where space is constrained.
