FMM-24R is listed in the Diode Arrays range at ChipApex. The manufacturer field lists Sanken Electric USA Inc.. Its product description is DIODE ARR GP 400V 10A TO-220F-2L. Review the specifications below when checking this part for your BOM.
The FMM-24R is a silicon diode with a resin-molded structure designed for commercial frequency rectification. It features an average forward current rating of 10A and a peak reverse voltage of 400V. The device supports a transient peak reverse voltage of 450V and a peak surge forward current of 100A. Electrical characteristics include a maximum forward voltage drop of 1.1V at 5.0A and a thermal resistance of 4.0°C/W between junction and case. Operating temperatures range from -40°C to +150°C.
Verify the specific suffix R against the datasheet to confirm polarity marking and pin configuration. Ensure the component meets UL94 V-0 flammability requirements for the target assembly. Confirm that the 400V peak reverse voltage rating aligns with the circuit's maximum operating conditions. Check derating curves for case temperature limits when designing the thermal management system.
Select this component based on its 10A average forward current capacity and 400V reverse voltage rating. Consider the 4.0°C/W thermal resistance for heat dissipation planning. Verify compatibility with commercial frequency applications. Ensure the operating temperature range of -40°C to +150°C suits the environmental conditions.
