Single Zener Diodes Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm packaging configuration and compliance status. Ensure the ordering part number matches the required tolerance grade and package variant. Cross-reference datasheet revisions to confirm material composition and assembly changes prior to final procurement decisions.

Single Zener Diodes Selection Notes

Select this component when a stable 6.2 V reference is required with high precision. The ±2% tolerance distinguishes it from standard 5% variants. Verify that the through-hole SOD-27 package fits the board layout constraints. Confirm thermal management capabilities align with the 500 mW dissipation limit in the target application environment.

Single Zener Diodes Part Context

This device belongs to the BZX79 series of low-power voltage regulator diodes. The series offers a wide range of nominal working voltages from 2.4 V to 75 V. The 'B' designation indicates the normalized E24 ±2% tolerance series, providing higher accuracy compared to the C series. These diodes are widely used in general-purpose electronic designs requiring reliable voltage clamping or referencing.
