Single Zener Diodes Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required tolerance class and package type for the intended circuit design. Cross-reference part numbers with authorized distributors to confirm current availability and authenticity before procurement.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 5.1 V is required in low-power applications. The DO-35 package offers robust mechanical support for through-hole assembly processes. Consider the ±5% tolerance and power dissipation limits relative to the expected load current and ambient thermal conditions during system design.

Single Zener Diodes Part Context

This part belongs to the Nexperia BZX79 series of low-power voltage regulator diodes. The series comprises 37 types covering nominal working voltages from 2.4 V to 75 V. The BZX79-C designation indicates the approximate ±5% tolerance range within the normalized E24 series, distinguishing it from the tighter ±2% B-series variants.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include other BZX79-C variants with similar voltage ratings or the BZX79-B series for tighter tolerance requirements. Verify pinout compatibility and thermal characteristics when substituting.
