Procurement Notes

Verify component authenticity and datasheet alignment before procurement, as this part may be subject to end-of-life status or supply restrictions. Confirm that the specific suffix matches the required packaging format and compliance standards. Cross-reference official manufacturer documentation to ensure compatibility with existing design specifications and regulatory requirements.

Selection Notes

Select this component when a precise 200V regulation point is required with moderate power handling capabilities. Ensure the circuit design accommodates the specified thermal dissipation limits and operates within the defined temperature boundaries. Verify that the ±10% tolerance aligns with the system's voltage accuracy constraints.

Part Context

This component belongs to the Microsemi 1EZ series of single Zener diodes. These devices are characterized by their use in general-purpose voltage regulation tasks. The series typically offers various voltage options within a standardized axial package, providing designers with consistent mechanical and electrical characteristics across different voltage ratings.

Replacement Considerations

Consult official Microchip Technology substitution guides for verified equivalents. Generic replacements must match the 200V Zener voltage, 1W power rating, and DO-204AL package dimensions to ensure functional compatibility without redesigning the host circuitry.
