Procurement Notes
Verify the specific ordering suffix against official Infineon documentation to ensure correct variant selection. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure storage conditions meet specified humidity sensitivity levels to maintain component integrity before assembly.
Selection Notes
Select this module when designing systems requiring high current handling capabilities up to 640 A RMS. Ensure the cooling solution accommodates the thermal characteristics of the TO-200AA package. Verify that the gate drive circuit can supply the required 200 mA trigger current reliably under all operating conditions.
Part Context
This component belongs to Infineon's ECO Block module series, which emphasizes high blocking stability and guaranteed short-circuit failure functionality. It is part of a broader family of silicon thyristors designed for demanding industrial power electronics applications where reliability and high current capacity are critical design parameters.
Replacement Considerations
The T420N14TOF is listed as an alias for this part number. Verify pinout compatibility and mechanical dimensions before substituting with other 1400V 420A SCR modules from different manufacturers.
