Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official Micro Commercial Components documentation to confirm tolerance levels and packaging options. Confirm that the component meets required environmental standards for the intended application. Ensure sourcing from authorized distributors to guarantee authenticity and traceability. Review the manufacturer's life support policy before deployment in critical systems.

Single Zener Diodes Selection Notes

Select this component when an 8.7 V regulation point is required in through-hole designs. Consider the 5% voltage tolerance and the specific thermal derating characteristics above 50°C. Evaluate the package dimensions against available board space. Compare the impedance and leakage specifications against circuit requirements to ensure adequate performance margins.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500 mW Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 75 V. All devices share common physical dimensions and electrical testing conditions, differing primarily in their nominal breakdown voltage and associated impedance values.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 8.7 V Zener diodes in the DO-35 package. Verify matching electrical parameters such as test current, impedance, and leakage. Ensure the replacement part maintains the same thermal and mechanical specifications for direct substitution.
