• High thermal stability suitable for elevated temperature environments

Single Zener Diodes Applications

• Low voltage stabilizers
• Voltage references
• General purpose voltage regulation circuits

Single Zener Diodes Procurement Notes

Verify the specific manufacturer part number against official onsemi documentation to ensure authenticity. Confirm that the ordering suffix matches the required packaging configuration. Check for RoHS compliance status and verify the manufacturing date code against project requirements. Ensure the component source is authorized to prevent counterfeit risks.

Single Zener Diodes Selection Notes

Select this component when a stable 9.1 V reference is required in a through-hole design. The DO-35 package offers robust mechanical handling compared to surface mount alternatives. Consider the 500 mW power rating for thermal management in the final circuit layout. Verify that the ±5% tolerance meets the precision requirements of the application.

Single Zener Diodes Part Context

This device belongs to the BZX79 series of low-power voltage regulator diodes. The series provides normalized E24 working voltages ranging from 2.4 V to 75 V. The 'C' designation indicates an approximate ±5% tolerance range, distinguishing it from the tighter ±2% B-series variants. These diodes are widely used in general electronic equipment requiring reliable voltage clamping or referencing.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering BZX79C9V1 equivalents in the DO-35 package. Verify pinout compatibility and thermal characteristics before substitution. Ensure the replacement part maintains the same 9.1 V nominal voltage and 500 mW power dissipation rating.
