Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the manufacturer's documentation to ensure correct tolerance and packaging specifications. Confirm that the TR suffix aligns with tape and reel handling procedures. Cross-reference the part number with the official datasheet to validate electrical characteristics before integration into production systems.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a tight temperature coefficient near 0.002 %/°C is required. Ensure the circuit design accommodates the specified 1.0 mA test current to maintain optimal stability. Verify that the DO-7 package dimensions fit the intended PCB layout constraints.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. These components are JEDEC registered and provide various temperature coefficient options around the 6.4 V nominal voltage. The series includes military qualifications and is designed for high-reliability applications.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N4571A and 1N4573A, which share similar voltage ratings but differ in temperature coefficients and test currents.
