sst211 sounds interesting: who makes them?
Try SST211.
I like them. They have 4 legs and are cute. What more could you ask for?
The substrate connection has to be more negitive than the source or drain
ever are. They are quite fast. 2nSis claimed but they seem to go faster
than that if the gate drive has very low impedance. Vgs(on) is only 1.5 so
it, I think, will meet the low voltage requirements.
The downsides of the SST211 are (1) they are easy to break and (2) the gm
is much lower than a power MOS-FET's.
