Single Zener Diodes Procurement Notes

Verify the specific suffix 'QR' against the manufacturer's latest documentation to confirm reel packaging specifications. Ensure the design accounts for the AEC-Q101 qualification requirements if deployed in automotive environments. Confirm that the SOT-23 footprint matches the standard soldering guidelines provided in the datasheet.

Single Zener Diodes Selection Notes

Select this component when a precise 2.2 V reference is required in space-constrained designs utilizing the SOT-23 package. The C-series designation indicates approximately ±5% voltage tolerance. Consider the low test current specification for efficiency in battery-operated systems where minimal quiescent current draw is critical.

Single Zener Diodes Part Context

This part belongs to the BZX8450-Q series of low-current voltage regulator diodes manufactured by Nexperia. The series covers a working voltage range from 1.8 V to 51 V. The BZX8450-C2V2-QR specifically represents the 2.2 V variant within the C-tolerance sub-group, packaged in the compact SOT-23 plastic surface-mount format.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include BZX8450-B2V2-QR, which shares the package but offers tighter ±2% voltage tolerance. Other voltage variants in the BZX8450-Q series may serve as functional replacements if the circuit allows for different reference voltages.
