Procurement Notes
Verify the specific suffix configuration against the official datasheet to ensure compatibility with required tolerance and packaging specifications. Confirm that the DO-35 through-hole package aligns with the target PCB layout constraints. Cross-reference the manufacturer's latest documentation to validate any updates to electrical characteristics or environmental compliance status prior to finalizing component selection.
Selection Notes
Select this component when a stable 6.4V reference with low temperature drift is required. Ensure the circuit design accommodates the specified 2mA test current for optimal performance. Verify that the operating temperature range meets the application's environmental demands. Consider the DO-35 package size for mechanical fit within the assembly.
Part Context
This part belongs to the 1N4565 through 1N4584A series of Zero-TC Reference Diodes produced by Microchip Technology. These devices are engineered to provide highly stable voltage references with minimal variation due to temperature changes. The series includes various options for different operating currents and tolerances, catering to diverse precision analog circuit requirements.
Replacement Considerations
Consult the official datasheet for parameter-equivalent alternatives within the same series or from other manufacturers. Verify that any substitute matches the 6.4V nominal voltage, 2mA test current, and DO-35 package dimensions.
