Single Zener Diodes Procurement Notes

Verify the specific suffix 'QR' against the manufacturer's latest documentation to confirm packaging details and availability status. Ensure the component matches the required AEC-Q101 qualification level for your target application environment. Cross-reference the marking code '%RJ' with official Nexperia tables to validate authenticity upon receipt.

Single Zener Diodes Selection Notes

Select this component when a precise 4.7 V reference with tight ±2% tolerance is required in a compact SOT23 footprint. The B-series designation indicates optimized performance for low-current regulation with minimal leakage. Consider the thermal resistance values if operating near the maximum power dissipation limit in confined spaces.

Single Zener Diodes Part Context

This part belongs to the PZU84-Q series of general-purpose Zener diodes designed for surface-mount technology. The series offers a wide working voltage range from 2.4 V to 51 V. The PZU84-B4V7-QR specifically targets applications requiring high precision and automotive reliability standards within a small plastic package.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other PZU84-B variants with different voltage ratings. For equivalent performance in automotive contexts, verify AEC-Q101 compliance. Non-qualified equivalents may lack the specified leakage or impedance characteristics.
