Procurement Notes
Verify the specific ordering code suffix against official documentation to confirm tape and reel specifications. Ensure that the commercial grade designation aligns with project requirements, as automotive-grade variants utilize different suffixes. Cross-reference the manufacturer's latest datasheet revision to validate all electrical parameters prior to final procurement decisions.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required in a compact SOT-23 footprint. The 30 V nominal rating suits applications needing precise voltage regulation within a narrow tolerance band. Consider the thermal resistance characteristics if operating near the upper limits of the specified ambient temperature range.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers a wide range of standardized voltage values packaged in the SOT-23 form factor. Variants exist with tighter tolerances and automotive qualifications, providing flexibility for diverse industrial and consumer electronics applications.
Replacement Considerations
Direct substitutes include other AZ23 series parts with identical pinouts and similar electrical characteristics. Verify that any replacement maintains the dual common anode configuration and matches the required Zener voltage tolerance for the specific application context.
FAQ
