Procurement Notes

Verify the specific manufacturer source, as Microchip acquired Microsemi assets which may influence part numbering conventions. Confirm RoHS compliance status directly with the supplier documentation. Ensure the DO-41 package type matches your PCB footprint requirements before finalizing procurement orders to avoid assembly issues.

Selection Notes

Select this component when a 10V regulated output is required with strict accuracy needs. The 1W power rating suits moderate current applications. Consider the through-hole DO-41 form factor if surface mount alternatives are not feasible. Verify thermal management capabilities align with the expected operating environment and load conditions.

Part Context

This part belongs to the standard Zener diode family used for basic voltage control. It serves as a fundamental discrete semiconductor component in mixed-signal designs. The designation indicates a specific voltage and tolerance variant within the broader product line, offering a cost-effective solution for general-purpose regulation tasks.

Replacement Considerations

Check for equivalent parts from other manufacturers offering identical 10V, 1W specifications in the DO-41 package. Ensure pinout compatibility and thermal characteristics match the original design requirements before substituting.
