Hi,
I have a problem reading the datasheet, so I would really appreciate some help.
For example: IRF630
The maximum rating for V(gs) (gate source voltage) is +- 20V
The mosfet will turn on when V(gs)th (gate treshold voltage) is 2/3/4 (min/typ/max)
How to interpret this?
What I assume is that if V(gs) is 0-1.999V the mosfet will be closed (ds resistance infinite in theory) and if V(gs) is between 2 and 4V the mosfet will open (ds resistance <0.5R).
But, the part that I do not get, if the maximum rating for V(gs) is +-20V I assume that if V(gs) is for example 10V, the mosfet will "open" and when V(gs) goes to for example -10V the mosfet will close.
I attached the parts of the datasheet that are confusing to me.
Another thing I would like to confirm (just to know I understand this correctly), mosfet is "open" or "closed", there are no "in between states" like with transistor, when I the potential difference between gate and source is > 2V it will open, and DS resistance is "same" for 2V and for 4V, right? it does not corellate as with transistor (ok transistor correlates base current but this is just analogy)?
thanks in advance
