Procurement Notes
Verify component authenticity against official Microchip Technology documentation. Confirm that the specific suffix matches the required reel packaging format. Ensure procurement channels provide valid traceability records. Cross-reference datasheet revisions to guarantee parameter consistency. Validate compliance with specified environmental standards prior to integration.
Selection Notes
Select this component when precise voltage stability under varying thermal conditions is required. The temperature compensation characteristic distinguishes it from standard Zener diodes. Verify that the 400 mW power dissipation aligns with the target circuit's thermal budget. Ensure the axial leaded package fits the designated PCB layout constraints.
Part Context
This part belongs to the Microchip Technology Zener Diode product line. It serves as a specialized voltage regulator within the broader diode and rectifier category. The designation indicates a specific voltage rating and packaging variant within the manufacturer's discrete semiconductor portfolio.
Replacement Considerations
Consult official Microchip substitution guides for verified equivalents. Generic replacements may lack the specific temperature compensation characteristics. Verify pinout compatibility and thermal performance before implementation.
