Procurement Notes

Verify the specific suffix N1 against official datasheets to confirm pinout and terminal configuration. Confirm RoHS compliance status through manufacturer documentation prior to integration. Check for end-of-life notifications or discontinuance notices from IXYS to ensure long-term availability for production cycles.

Selection Notes

Select this module when an 800V blocking capability and 172A continuous current are required. Ensure the cooling solution supports the thermal resistance specifications of the Y4-M6 package. Verify that the system's peak reverse voltage does not exceed the 800V rating under all operating transients.

Part Context

This component belongs to the MDD series of high-current diode modules manufactured by IXYS. The series is characterized by silicon planar chip technology and is engineered for durability in industrial power electronics. The MDD172-08N1 specifically addresses applications requiring reliable rectification at moderate voltage levels with high current throughput.

Replacement Considerations

Consult official cross-reference guides for direct substitutes. Modules such as the MDD220-16N1 offer higher ratings but may require different mounting considerations. Verify electrical compatibility and physical dimensions before substituting.
