Single Zener Diodes Procurement Notes

Verify the specific ordering suffix, such as -18, against official Vishay documentation to confirm the correct tape-and-reel quantity and packaging configuration. Ensure that the AEC-Q101 qualification status aligns with your project's automotive compliance requirements before finalizing procurement decisions.

Single Zener Diodes Selection Notes

Select this component when a precise 9.1 V reference is required in space-constrained automotive designs. The DO-214AC package offers robust soldering capabilities for automated assembly processes. Consider the 1.25 W power rating for thermal management in high-current environments where standard low-power diodes may fail.

Single Zener Diodes Part Context

This part belongs to the BZG05B-M series of single Zener diodes from Vishay. The series is designed for general-purpose and automotive applications requiring reliable voltage regulation. The BZG05B9V1 variant specifically targets the 9.1 V breakdown voltage segment within this lineup.

Single Zener Diodes Replacement Considerations

Cross-reference with other Vishay parts in the BZG05B-M series or equivalent AEC-Q101 qualified Zener diodes from other manufacturers. Verify pinout compatibility and ensure the replacement meets the same 1.25 W power and 9.1 V voltage specifications.
