It's too big, costs a lot and it doesn't behave that well at higher temperatures, so we are looking to replace it. After scanning through STMicroelectronics, Powerex and Ixys components I believe I found a fine replacement: https://ixapps.ixys.com/DataSheet/CLA80E1200HF.pdf
Has anyone had any experience with this component?
Can you maybe suggest something else in this domain of currents and temperatures?
Finally, a PSpice model of any of these would be great help - could you at least point where to look for one?
the IXYS part has lower I2T and lower peak current capability, it the currents are bounded to less than 800A pk and 80A rms then it will be OK if properly heatsunk.

large SCR's are not suited to high temp operation ~ 100 deg C case for many of them - this is because the gain of the SCR goes up with temp and it can self trigger due to external dV/dT at elevated temps ...
Silicon Carbide has been the Tantalum(*) of power electronics for several years now.......But for one reason or another widespread usage has failed to materialize.
(*) Meant in the sense of the Greek mythology punishment, not of the more familiar capacitor material.
I was in a hurry back then, but I just wanted to express gratitude to all of you for information - especially since I learned about the new product here.
