Procurement Notes

Verify the specific manufacturer source, as the component history involves transitions between Microsemi and Microchip Technology. Confirm RoHS compliance status and package type (DO-35 or similar axial lead) against current datasheets. Ensure the selected variant matches the required temperature coefficient specifications for your application environment.

Selection Notes

Select this component when high stability and low noise are critical requirements. The 12.8 V nominal voltage is ideal for applications requiring precise reference levels. Consider the 400 mW power rating for thermal management in enclosed spaces. Verify that the axial through-hole package fits the PCB layout constraints.

Part Context

This part belongs to the JEDEC registered 1N4896 through 1N4915 series of temperature compensated Zener diodes. These components are designed to provide a stable reference voltage despite temperature fluctuations. The series is widely used in instrumentation and measurement equipment where accuracy is paramount.

Replacement Considerations

Check for direct equivalents within the 1N4896-1N4915 series from other manufacturers. Verify pinout compatibility and thermal characteristics before substitution. Ensure the replacement maintains the same low noise and temperature compensation properties.
