Single Zener Diodes Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q101 qualification when sourcing. Confirm the 'C' designation corresponds to the approximate ±5% tolerance series rather than the tighter ±2% variant. Ensure the ordering part number matches the required nominal voltage and package type for accurate procurement.

Single Zener Diodes Selection Notes

Select this component for circuits requiring precise voltage reference or regulation under minimal bias conditions. The SOD523 package is appropriate for space-constrained layouts. Consider the thermal resistance characteristics if operating near the maximum power dissipation limit in free air versus mounted on a PCB.

Single Zener Diodes Part Context

This component belongs to the BZX58550-Q series of low-current voltage regulator diodes manufactured by Nexperia. The series offers a wide range of nominal voltages from 1.8 V to 51 V in the compact SOD523 package. The '-Q' suffix denotes automotive qualification, while the middle letter indicates the tolerance grade.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other BZX58550-Q series variants with matching voltage and tolerance, such as BZX58550-B8V2-QX for tighter tolerance. Cross-reference with other manufacturers' SOD523 Zener diodes ensuring equivalent electrical ratings and AEC-Q101 compliance if automotive reliability is required.
