Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' against official Microchip documentation to confirm exact mechanical or testing variations. Confirm RoHS compliance status directly with the manufacturer as historical data may vary. Ensure the required operating temperature range aligns with the specified -65°C to +175°C limits before integration into final assemblies.

Single Zener Diodes Selection Notes

Select this component when a stable 9.1 V reference is required under varying thermal conditions. The low test current of 0.5 mA makes it suitable for battery-powered or low-power consumption designs. Verify that the 500 mW power rating is sufficient for the expected load conditions within the specified temperature range.

Single Zener Diodes Part Context

This part belongs to the 1N4765 through 1N4774A series of temperature-compensated Zener diodes produced by Microchip. These devices utilize double-plug construction and metallurgical bonding to achieve superior temperature stability compared to standard Zener diodes. They are intended for applications requiring high accuracy over wide temperature spans.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 9.1 V temperature-compensated Zener diodes in the DO-35 package. Verify that substitute parts meet the same 0.5 mA test current and ±5% tolerance requirements to maintain circuit performance.
