Procurement Notes
Verify the specific datasheet version and technical specifications directly from Infineon or authorized distributors before procurement. Confirm that the disc dimensions and clamping force requirements match the intended mechanical assembly. Ensure compliance with local import regulations and environmental directives such as RoHS and REACH. Check for any obsolescence notices or lifecycle status updates from the manufacturer.
Selection Notes
Select this component based on its 4500 V voltage rating and 172 mm disc form factor. Evaluate thermal resistance and cooling requirements against the application's heat dissipation needs. Consider the mechanical clamping pressure limits specified in the assembly instructions. Compare performance metrics with alternative high-power SCR models if system constraints require different current ratings or package sizes.
Part Context
This part is part of Infineon's high-power thyristor and diode portfolio, specifically the D3900 series. These components are engineered for extreme electrical stress conditions. The D3900U45X172XPSA1 variant represents a specific configuration within this family, distinguished by its voltage class and physical dimensions. It serves as a critical switching element in heavy-duty industrial and energy infrastructure applications.
Replacement Considerations
Consult official Infineon documentation for cross-reference data. Verify compatibility of pinout, voltage ratings, and thermal characteristics when substituting with other high-power SCRs. Ensure mechanical fitment matches the 172 mm disc specification.
