Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the manufacturer's datasheet to ensure correct tolerance and qualification levels. Confirm that the ordering part number aligns with the desired JEDEC registration or military standards. Check for RoHS compliance status if required by the manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.005%/°C temperature coefficient is required. Ensure the operating current matches the specified 1.0 mA test condition for optimal stability. Consider tighter tolerance suffixes if standard 5% voltage accuracy is insufficient for the application.

Single Zener Diodes Part Context

This device belongs to the 1N4565 thru 1N4584A series of zero-TC reference diodes. These components provide a selection of nominal 6.4 V voltages with varying temperature coefficients and operating currents ranging from 0.5 mA to 4.0 mA. They are designed for high-reliability applications requiring precise voltage regulation.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N4571 variants such as 1N4571A or 1N4571-1. Verify that replacement devices match the 6.4 V nominal voltage, 1.0 mA test current, and 100 Ω dynamic impedance specifications.
