Single Zener Diodes Procurement Notes

Verify the specific suffix BUR-1 against official Microchip documentation to confirm that it denotes the standard 5% tolerance variant rather than a tighter tolerance or specialized screening level. Ensure the ordering quantity aligns with the manufacturer's reel packaging requirements. Confirm RoHS compliance status through the latest datasheet before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 18 V regulation point is required in a surface-mount design. The DO-213AA package offers space efficiency compared to axial leads. Verify that the 500 mW power rating meets the thermal dissipation needs of the target circuit under worst-case operating conditions and ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of glass-passivated Zener diodes produced by Microchip Technology. The series provides a wide selection of voltage values ranging from low voltages up to 200 V. These components are widely used in discrete semiconductor designs where reliable voltage clamping and regulation are necessary.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SMA-packaged 18 V Zener diodes with 500 mW ratings. Verify pinout compatibility and ensure equivalent Zener impedance and leakage current specifications match the original design requirements.
