Procurement Notes

Verify the exact ordering suffix against official Infineon documentation to ensure correct configuration. Confirm RoHS compliance status through the latest material content data sheet. Cross-reference the Mouser number 641-t740n26tof for accurate distributor identification during sourcing. Validate the datasheet version matches the required technical specifications before procurement.

Selection Notes

Select this module based on the specific requirement for 740 A continuous current and 2600 V blocking voltage. Ensure the thermal management system supports the device's power dissipation characteristics. Verify that the gate drive circuitry aligns with the thyristor's triggering requirements. Consider the physical dimensions of the TO-F package for mechanical integration into the assembly.

Part Context

This component is part of Infineon's broader portfolio of silicon-based SCR modules designed for high-power industrial applications. It shares the core thyristor technology found in similar high-voltage series but is distinct due to its specific 740 A rating and 2600 V voltage class. The TO-F packaging provides a standardized interface for mounting and cooling solutions common in large-scale power electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternative models from the same manufacturer only if they match the 740 A and 2600 V ratings exactly. Verify pin compatibility and thermal resistance values before considering any cross-brand replacements.
