[TCML] IGBT?

[jhowson4@xxxxxxxxxxx]

Hello all, 

I am attempting to figure out how to properly choose an IGBT for a SISG board. 
Not sure if I will be building one yet, but more of a learning and trying to figure everything out kind of thing. so I have been using my current coil as a base design, just for the purposes of figuring this out on paper. 

The schematic calls for an IRGPS60B120KDP 
But the current to pulse frequency characteristics are not listed in the datasheet. 

How does one determine if the IGBT will be acceptable for my particular coil set up? 
Java TC tells me that my primary current is close to 400 amps peak current (not that the coil that might be built would have that primary current) 
I read some where (wish I remembered where) that these were fine up to an 800amp primary peak current...is that way off base, and if not where did that number come from? 


I am having a similar issue with the SIDACs which I have been informed the proper replacement is called a TRISIL 
specifically this one http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATASHEET/CD00001359.pdf 

Once again I am not sure why. Probably because I don't understand the format. Like in the section labeled repetitive peak pulse current the value is defined as 10/1000 us being 30A at first i though that it was a simple fraction expressing that it could handle a 30 amp pulse every 10ns, but apparently that is not right per a random forum post I found... somewhere... So what exactly does 10/1000 mean? 



Thank you to anyone willing to help me learn, 
John "Jay" Howson IV
