Hi,
I wonder what do you think of this SiC mosfet. Has a triode-like behaviour In a interesting current range and fairly affordable.
Should be interesting use for an amplifier, something like a F3, maybe?

ok, sorta highish Ugs for area of our interest, lowish max current, but SOA graph - DC is not even mentioned
which implies - use it in DC domain and it's toasted

There is no tride-ish behavior. All of the curves are concave down which is pentode-ish.
The LU1014D is the only device that I have found with triode-ish curves and not marketed as an SIT.
IXTH80N075L2 is a linear DC SOA optimized mosfet with decent linearity and very high power handling capability.
It has maximum power dissipation is only 50W. So ideally it should be cascode like F3.
agree for that one, even Ugs looks not so high, even if higher than our common IRFP
though, is there any advantage over IRFP240 or 150, thing to find in vivo, comparing them in same circuits
It has a Ids that is concavish between 0 to 10V for current range that is about 2A. Compared to IRFP240 which would flat line at about 1V.
The topology in F3, as I understand it is, as Vgs increases, so does gain but at the same time, Vds decreases and that reduces gain. If done properly they would cancel out each other. At least that is in theory.
Besides, it is SiC and only a few bucks...
