I am looking for the replacement part numbers for four IGBTs removed from an inverter welder. The number on the components are K75T60. I am unable to determine if these have a flyback diode or not. The two part numbers I have found are IGW75N60T without diode, and IKW75N60T with diode.
I've attached pictures of the components and the circuit diagram. I don't think that the diagram accurately depicts what is included in the IGBT.
