Single Zener Diodes Procurement Notes

Verify the specific suffix 'QVL' against official Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component matches the required AEC-Q101 qualification status for your target application environment. Cross-reference the marking code '%B7' on the physical device to confirm authenticity and correct type identification before integration into production designs.

Single Zener Diodes Selection Notes

Select this component when a stable 51 V reference is needed in space-constrained designs requiring automotive-grade reliability. The SOT-23 package offers a compact footprint suitable for high-density PCB layouts. Consider the ±5 % tolerance and thermal resistance characteristics during circuit design to ensure performance stability across the specified operating temperature range.

Single Zener Diodes Part Context

This part belongs to the BZX84-Q series of low-power voltage regulator diodes manufactured by Nexperia. The series includes 37 breakdown voltages ranging from 2.4 V to 75 V. The 'C' designation indicates an approximate ±5 % tolerance range, distinguishing it from the higher precision 'A' (±1 %) and 'B' (±2 %) variants within the same family.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other BZX84-Cxx-Q parts with different Zener voltages if the voltage requirement changes. For identical specifications, verify availability of BZX84-C51-Q variants with different packaging suffixes.
