Procurement Notes

Verify the exact ordering suffix against official Infineon documentation to confirm pinout and thermal interface specifications. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the procurement channel provides valid traceability records for industrial-grade components.

Selection Notes

Select this module when an 1800V rating and 420A continuous current are required. Verify that the cooling system can handle the thermal dissipation characteristics specified in the datasheet. Ensure the gate trigger requirements align with the control circuit capabilities.

Part Context

This part is part of Infineon's T420N series of phase control thyristors. It shares the same current rating as the T420N16TOF but offers a higher voltage rating of 1800V compared to the 1600V variant. The TOF suffix indicates specific packaging and terminal configurations within the product family.

Replacement Considerations

Direct replacements include the T420N16TOFXPSA1 for lower voltage applications or the T560N18TOFXPSA1 for higher current requirements. Always verify mechanical dimensions and thermal resistance values before substituting.
