Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to confirm the presence of the internal metallurgical bond, as this affects mechanical robustness. Ensure the selected variant matches the required temperature coefficient and voltage tolerance for your application. Cross-reference the datasheet for absolute maximum ratings to prevent overstress during operation. Confirm package compatibility with your PCB layout constraints prior to ordering.

Single Zener Diodes Selection Notes

Select this component when precise voltage stability over temperature is critical. The 6.4 V nominal value is optimal for silicon bandgap references due to near-zero temperature coefficients. Consider the 4 mA test current requirement for biasing circuit design. Evaluate the DO-35 package size against available board space. Verify that the 500 mW power dissipation rating accommodates the expected thermal environment without excessive heating.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. These devices are engineered to provide stable reference voltages with exceptionally low temperature coefficients. The series offers various operating currents and voltage options within the glass DO-35 package. The -1 suffix denotes the availability of an internal metallurgical bond for improved durability compared to standard fused constructions.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other parts from the 1N4565-1 through 1N4584A-1 series offering similar 6.4 V characteristics. Verify that alternative components maintain the same DO-35 footprint and metallurgical bond construction if mechanical reliability is required. Ensure replacement devices meet the specified 1% voltage tolerance and 4 mA test current parameters.
