• High surge current capability with I2t limiting value
• Low thermal resistance for efficient heat dissipation

Diode Arrays Applications

• Commercial frequency rectification circuits

Diode Arrays Procurement Notes

Verify the specific suffix designation when ordering, as the FMM-24R variant shares identical specifications but may differ in marking or internal polarity indicators. Confirm that the requested quantity aligns with standard packaging configurations provided by the manufacturer. Ensure compliance with UL94 V-0 flammability requirements if applicable to the end-use environment. Cross-reference the lot number markings on received units against production records to verify authenticity and traceability.

Diode Arrays Selection Notes

Select this component for applications requiring robust performance at commercial frequencies with moderate power handling capabilities. The 400V reverse voltage rating suits general-purpose rectification tasks where high voltage isolation is not the primary constraint. Consider the derating curves for average forward current based on expected case temperatures to ensure reliable operation under varying thermal conditions without exceeding the maximum junction temperature limit.

Diode Arrays Part Context

This part belongs to the FMM-24 series produced by Sanken Electric Co., Ltd. The series includes variants such as the FMM-24R, which shares the same core electrical specifications and physical dimensions. These components are engineered for reliability in commercial electronics, utilizing a standardized package design that facilitates automated assembly and consistent thermal performance across different manufacturing batches.

Diode Arrays Replacement Considerations

The FMM-24R is documented as a parameter-equivalent alternative within the same product line. Verify that any substitute maintains the same 400V reverse voltage and 10A forward current ratings. Ensure the replacement component meets the same thermal resistance and flammability standards required by the original design specifications.
