Single Zener Diodes Procurement Notes

Verify the specific suffix 'QR' against the manufacturer's latest documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component meets the required AEC-Q101 qualification status for the intended automotive application environment. Cross-reference the marking code '%P4' with official Nexperia tables to validate authenticity and manufacturing origin before integration into production designs.

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 footprint. The ±2% tolerance offers tighter voltage accuracy compared to standard ±5% variants. Consider the low test current requirement (50 µA) to ensure compatibility with low-power biasing circuits where minimal quiescent current consumption is critical for system efficiency.

Single Zener Diodes Part Context

This part belongs to the BZX8450-Q series of low-current voltage regulator diodes. The series provides various Zener voltages ranging from 1.8 V to 51 V in the compact SOT-23 package. The 'B' designation indicates the ±2% tolerance series, distinguishing it from the 'C' series which offers approximately ±5% tolerance. All parts in this family share similar thermal and physical characteristics.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZX8450-C2V2-QR for ±5% tolerance or other B-series variants like BZX8450-B2V0-QR and BZX8450-B2V4-QR for slightly different voltage references. Verify pinout compatibility and thermal resistance values when substituting.
