Since transistors and Mosfets have some with minimum spec's and others with maximum spec's then some will work and some will not work if ALL of them are not sensitive enough for your voltages (because you cannot order only very sensitive ones, you get whatever they have). Look in Digikey where you can select "typical" spec's for Mosfets then look on the datasheet of the most sensitive Mosfet to see if ALL of them are sensitive enough.
