Reference design of CRD-30DD12N-K: SiC MOSFET C3M0040120K vs. C3M0075120K

Hello,

With respect to the reference design of CRD-30DD12N-K, I have a question on the SiC MOSFET on the main board.

The SiC MOSFET of C3M0040120K is employed for the rated power of 30kW for this reference design.

I wonder if the other SiC MOSFET instead of C3M0040120K might be able to be used when the rated power is less than 30kW for this reference design.

For instance, let us suppose that the rated power is 10kW.

Then may the SiC MOSFET of C3M0075120K be able to be used in place of C3M0040120K on the main board for this reference design?

Also, if C3M0075120K can be used on the main board, what would be the rated power for this reference design?

Thank you for your consideration.

With regards,

GKIM
