Single Zener Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. Standard versions are commercial grade. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes qualification status. Confirm that the requested variant matches the required reliability standard for your specific application environment before finalizing orders.

Single Zener Diodes Selection Notes

Select this component for designs requiring a compact surface-mount solution with a 39 V reference point. Ensure the PCB layout accommodates the SOD-123FL footprint and allows for adequate copper pad area (25 mm²) to support the rated 1 W power dissipation. Verify thermal management requirements against the specified operating temperature limits.

Single Zener Diodes Part Context

This part belongs to the MM1Z47xxA series of SMD Planar Zener Diodes from Diotec Semiconductor. The series covers a wide voltage range from 3.3 V to 47 V, all sharing the same low-profile SOD-123FL package and 1 W power rating. This family is designed for general-purpose commercial and industrial electronic applications.

Single Zener Diodes Replacement Considerations

Direct functional equivalents may be found among other manufacturers offering 39 V Zener diodes in the SOD-123FL package. However, verify that alternative parts match the specific dynamic resistance, leakage current, and thermal resistance specifications to ensure circuit performance parity.
