Minimum driving voltage for SiC MOSFET

What would be a minimum driving voltage requirement for your SiC MOFET. I saw a picture in Onsemi's datasheet, showing the relationship between Rdson as a function of gate driver voltage, at different temperatures.

Do you have a similar curve for your SiC MOSFET?

Thanks.

    Welcome, @BLu.4​, to the community!

    Well, that's a question of point of view: SiC datasheets from STMicroelectronics contain something comparable - the Transfer characteristics, i.e. the dependence of the drain current on the gate-source voltage at several temperatures, e.g. at 200 DEGC. The question now is which is more relevant in practice.
