Single Zener Diodes Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm the exact packing configuration associated with the part number. Ensure that the required Zener voltage tolerance aligns with the design specifications before procurement. Cross-reference the package dimensions with the target PCB layout to ensure mechanical compatibility during assembly.

Single Zener Diodes Selection Notes

Select this component when a precise 27 V reference is required in a through-hole environment. The BZX79-C series provides approximately 5% tolerance, suitable for general regulation tasks. Consider the 500 mW power rating and thermal management requirements for the specific circuit application to ensure reliable operation under load conditions.

Single Zener Diodes Part Context

This component belongs to the BZX79 family of low-power voltage regulator diodes manufactured by Nexperia. The series offers various nominal working voltages ranging from 2.4 V to 75 V. These devices are designed for use in compact electronic systems requiring reliable voltage clamping or referencing capabilities within standard axial leaded packages.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' DO-35 packaged Zener diodes with matching 27 V nominal voltage and similar power dissipation ratings. Verify that alternative parts meet the same electrical tolerances and thermal performance characteristics.
