They're designed purely for switching but have a pretty modest Vt, which should make some here quite happy. Not sure how they behave in linear applications, but obviously their eye watering current capabilities are going to be markedly reduced. Also can't remember how their parasitic capacitances sit in comparison with competitors options.
Long story short: don't know!

The transconductance is pretty high and the threshold voltage is quite low.
I wonder how well it'll work in a cap multiplier.

I saw them described as a hybrid incorporating characteristics of lateral mosfets.
That could mean nothing to someone who understands semiconductors.

The TO220 package will limit their power capacity.
For power amps I would be look for at least a to247 package.

Not so much in this case. RθJC is 0.6 °C/W, better than IRFP240 at 0.83 °C/W. Simply use really good insulator like Keratherm.
That's all well and good, but TI's NextFET don't come in that package: N-Channel MOSFET Transistor | Overview | Power ICs | TI.com
What about paralleling if they have worthwhile attributes? What's about cascoding?
The price seems right at a few dollars each.

If you're looking for new power transistors and are perhaps willing to step back a little bit from a "Pass-traditional" level of bias, they might work just a treat. We don't know their linear properties.
And yes, of course you can parallel them with all the caveats of paralleling output transistors.

Yep, that's what I've been meaning in terms of "linear properties", i.e. not using them as a switch. 🙂 Since TI is selling these chips for switching, they didn't publish those curves. Will require some enterprising individual to publish those for us to use.
