How to simulate the SCT2450KE Rohm SiC mosfet model in LTspice
First check that pins 1,2,3 are what you think they are.
From the Spice listing...
* SCT2450KE
* SiC NMOSFET model
* 1200V 10A 450mohm
* Date: 2015/12/07
******************D G S
.SUBCKT SCT2450KE 1 2 3

Notice anything about the last 2 lines?
Second, what is a 1000V supply and a 10 ohm load going to do to a 10A device?
