Procurement Notes

Verify the exact suffix against official Infineon documentation, as variations may indicate specific testing or packaging configurations. Confirm RoHS compliance status through the manufacturer's material declaration. Ensure the ordering part number matches the required voltage and current ratings for the target application before procurement.

Selection Notes

Select this component for high-power AC/DC conversion circuits requiring precise phase control. Evaluate the thermal resistance and cooling requirements based on the 740 A continuous current rating. Ensure the gate drive circuit can supply the specified trigger parameters within the operational temperature range.

Part Context

This model belongs to Infineon's high-power thyristor disc series, designed for heavy-duty industrial applications. It shares the physical form factor with other devices in the T740N family but differs in blocking voltage and current handling capabilities. The TO-200AB package is standard for modules requiring direct heatsink mounting.

Replacement Considerations

Direct replacements must match the 2600 V / 740 A specification and TO-200AB footprint. Verify compatibility with existing gate drive circuits and thermal interface materials. Cross-reference with Infineon's selection guide for equivalent performance in voltage and current ratings.
