Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm exact electrical parameters and packaging details. Ensure that the component matches the required voltage and current ratings for the target application before procurement. Cross-reference the datasheet version to validate thermal resistance values and switching characteristics.

Selection Notes

Select this module based on its 1600 V blocking capability and 400 A continuous current rating. Evaluate the thermal management requirements considering the specified package size and heat dissipation needs. Confirm compatibility with existing gate driver circuits and ensure the switching frequency aligns with the device's dynamic performance specifications.

Part Context

This component belongs to the FF/FS/FD series of 62 mm IGBT modules. It shares mechanical dimensions with other modules in this family, facilitating board layout reuse. The FD prefix typically denotes a half-bridge configuration within the product line, distinguishing it from single switch or three-phase variants.

Replacement Considerations

Direct replacements include the FD400R16KE4 and FD400R16KS4. Verify pinout compatibility and thermal interface material requirements when substituting. Check if the alternative variant offers improved switching speed or lower conduction losses suitable for the specific application.
