Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm tolerance and packaging variations. Ensure compliance with RoHS status requirements as indicated in the manufacturer's environmental declarations. Cross-reference the component number with authorized distributors to validate authenticity and traceability before integration into production schedules.

Selection Notes

Select this component when circuit designs require precise regulation at 160 V with moderate power handling capabilities. Consider the DO-204AL package dimensions for PCB layout constraints. Evaluate the thermal management requirements given the 1.25 W dissipation rating and the wide operating temperature range to ensure reliability under extreme conditions.

Part Context

This component belongs to the standard Zener diode family manufactured by Microchip Technology. It serves as a discrete semiconductor solution for maintaining constant voltage levels in electronic systems. The part is distinct from switching or signal diodes due to its specific breakdown voltage characteristics and power handling abilities.

Replacement Considerations

Consult official substitution lists for equivalent parts with matching voltage and power ratings. Verify pin compatibility and thermal performance before replacing the original component in existing designs.
