Procurement Notes

Verify the specific part number against official IXYS documentation to confirm technical specifications before procurement. Ensure that the required voltage and current ratings align with the system design parameters. Check for any product change notifications or updates regarding the manufacturing process. Confirm compliance with relevant safety standards such as UL registration E72873. Validate mechanical dimensions and mounting torque requirements for integration.

Selection Notes

Select this module when high current capacity and reliable thermal dissipation are critical. The planar chip technology and ceramic base plate offer improved resistance to temperature cycling compared to traditional designs. Consider the specific conduction angles and case temperatures to accurately determine the continuous current rating. Evaluate the surge current capabilities for potential fault conditions in the circuit design.

Part Context

This component belongs to the MDD 310 series of high-power diode modules manufactured by IXYS. The series includes variants with different voltage ratings, such as the MDD310-14N1 and MDD310-20N1, allowing for flexibility in system design.
