Diode Arrays Procurement Notes

Verify the specific suffix 'SA2' against official Infineon documentation to confirm exact manufacturing lot details and compliance status. Confirm availability through authorized distributors as supply may be restricted in certain regions. Ensure proper mounting torque specifications are followed during installation to maintain thermal performance and mechanical integrity.

Diode Arrays Selection Notes

Select this component when a 1200 V rating is required for rectification in high-current circuits. Compare thermal resistance values against system cooling capabilities. Ensure the housing size fits the available space in the converter design. Verify that the forward voltage characteristics align with efficiency targets for the specific application load profile.

Diode Arrays Part Context

This part belongs to the DD171N series of bipolar semiconductor modules. It shares the same physical footprint and general technology family with variants like DD171N16K, differing primarily in voltage ratings. The series is characterized by its use of pressure contact technology and standardized dimensions for easy integration into existing power electronics platforms.

Diode Arrays Replacement Considerations

Check for direct cross-reference part numbers in Infineon's official substitution guides. Consider modules with identical housing dimensions and pinout configurations if sourcing from other manufacturers. Verify that alternative parts meet or exceed the 1200 V and 170 A requirements.
