I've been shopping for some mosfet transistors, for a starter kit, and noticed listings that state a mosfet is suitable for 5v logic, but the data sheets says Gate Threshold is 1-2v.
4v gated mosfets, which are closer to 5v, by the same seller are not advertised as suitable.
I understand that applying Vgs voltage to the gate will switch the mosfet on, but how does it interact with different voltages?
So for example if a mosfet had Vgs range of 2-3 and I applied voltage ranges of 0-1,2-3,3-7 to it I assume it would go something like this (correct me if I'm wrong):
- 0-1v – off
- 2-3v – on with proportional conductivity (with 3v having maximum).
- 3-7v – heat/burn?
