Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation as the provided model references Microsemi, while official documentation often lists this component under Microchip Technology due to corporate acquisition. Confirm RoHS compliance status and ensure the package type matches the required DO-215AA footprint before integration into designs.

Single Zener Diodes Selection Notes

Select this component when a 10 V regulation point is required in a surface-mount configuration. The 2 W power rating allows for higher current handling compared to smaller packages like SMA or SOD-123 types. Ensure the operating environment supports the specified wide temperature range for reliable performance.

Single Zener Diodes Part Context

This part belongs to the SMBG series of Zener diodes, which are plastic-encapsulated devices intended for general-purpose voltage regulation. The series offers various voltage options within the same physical footprint, facilitating design flexibility across different product lines requiring standardized board layouts.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 10 V, 2 W Zener diodes in the DO-215AA package. Verify that any substitute meets the same electrical specifications regarding Zener impedance and leakage current to ensure circuit compatibility.
