700 volts, turns on to 10 amps with +5 on the gate, reverse transfer
capacitance 0.3 pF, cheap.
 
 

Yeah, $1.64 in hundreds, pretty good for what you get.  Analog switch FOM
C_dg*R_on is about 1 ps, very impressive.

I want its little brother, with that sort of speed and a g_m of 200 mS.
Assuming it’s quiet, of course—apart from extrinsic effects it should be
about sqrt(8/3 * kT/g_m) = 0.22 nV in 1 Hz.
