How low it "can" be is immaterial, how high it might be is
more relevant to circuit design if you're not hand-picking
parts for that quality.
GIDL (gate induced drain leakage) is a thing in some types
of MOSFETs (though I've seen it more in integrated, plain
FETs). That means after some distance into negative Vgs,
drain current increases from its minimum.
Gate curreent is always very low and independent of drain voltage, since the gate looks like a capacitor.I am clearly asking about MOSFETs, so gate current should be much smaller than drain current.
