WebThe Cutoff Voltage of a JFET is the voltage that is needed at the gate-source region of the JFET in order to turn it off. At this point, the transistor enters the cutoff region . For JFETs, the cutoff voltage is referred to as V GS,off, because it is the voltage which must be applied to the gate-source terminal to turn off the transistor. Webin insulated-gate field-effect transistors (IGFET), "pinch-off" refers to the channel pinching that leads to current saturation behaviour under high source–drain bias. in junction field …
