SiC JFETs from United SiC are very useful, but the TO247 package is very large. The dice are very small at about 1.1mm square.
Is it beyond riches to have say a hundred dice packaged in SOT-223, are there places that do this?
Totally outside my experience.

Yes, dice bonding in WuHan. But you will be playing dice with your life.
Here's a Cree SiC fet:
Seems silly to put that into a giant TO247 package.
Compare that to some silicon parts:
Not enough parts come in SOT-89.

Rohm and United SiC both offer TO-220 parts.

At least big packages prevent installing multiple dices too close together :-). Getting the heat out to a large heatsink is an issue.
But not their JFETs.
Sure I could do it other ways, but for this application, a normally-on, high-voltage, reasonably fast analog switch with -ve a few volts to switch off fits so well in all but size.
