    what is the the exact defination of "pinch off voltage " in JFET..
    is it function of VDS or VGS?
    some books says that at pinch off state ID is zero....
    if it is a function of VDS then why the VP are taken as negative ...
    in data sheet VGS(off) are called pinch off voltage ...
    plz explain which one is correct......

    the point from which the current downfall is start that point is called pinchoff point and corrosponding voltage is called pinchoff voltage.
    Are you sure? This action cannot be undone.
