Re: [TCML] IGBT CM600 max current ?

[Derek <tesla@xxxxxxxxxxxxxxxxxxxxxxxx>]

Chris,
   My last OLTC ran a CM300 in the 600-800A range for a number of years 
w/o any issues. So I would assume you could abuse a CM600 to 1.2KA in TC 
duty with no problems. I assume the 1.4KA on the PDF is their pulse 
rating if ,so 1.5-1.6KA is probably the area I would go for.

I don't think that they are as resilient as a smaller die IGBT due to 
localised heating. I know with some smaller devices you can run to 2x 
the pulse rating with no issues.

All of the above assumes a very small mark/space ratio of course..
  
   Cheers
      Derek
