Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm package type and reel specifications. Ensure the procurement channel provides valid manufacturer traceability. Confirm RoHS compliance status as indicated in the product specification sheet prior to ordering.

Selection Notes

Select this component when precise voltage referencing is required alongside high thermal stability. The low temperature coefficient makes it superior to standard Zener diodes for applications experiencing significant ambient temperature fluctuations. Verify that the 400 mW power dissipation rating aligns with the circuit's thermal management capabilities.

Part Context

This part belongs to the Microchip Technology discrete semiconductor portfolio, specifically within the Zener diode category. It serves as a specialized voltage reference solution distinct from general-purpose rectifiers or standard regulation diodes. The component supports legacy and modern designs requiring robust performance in harsh operational environments.

Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Cross-referencing requires matching Zener voltage, tolerance, package style, and thermal coefficients to ensure functional compatibility without circuit modification.
