Wikipedia tells me HVDC runs at 100s of kilovolts. What kind of semiconductor can handle that without promptly turning into plasma?

Big ones, usually made of silicon carbide.

My understanding is that the semi's are stacked so that any individual switch only sees a voltage it can handle, with safeguards to cut off the whole mess on failure.
