Pinch-off效应
WebJun 1, 2024 · As Drain-source voltage is increased, it attracts the electrons from source end to drain end and current flows from Drain to Source, in this case, we're in the triode region. As the Vds increases, we reach a point where Vds=Vgs-Vth that is pinch-off, at which the current becomes saturated and almost constant current flows.

http://www.ichacha.net/pinch-off.html WebFurther increasing the source-drain voltage will not substantially increase the current because the potential at the pinch-off point remains V g − V th and thus the potential drop between that point and the source electrode stays approximately the same, and the current saturates at a level I ds,sat (Fig. 25.7(d)).

In JFET, the current flow is due to the majority of charge carriers. However, in BJTs, the current flow is due to both minority and majority charge carriers.

WebFor example, V GS(off) for the Temic J202 device varies from −0.8 V to −4 V. Typical values vary from −0.3 V to −10 V. (Confusingly, the term pinch-off voltage is also used to refer to the V DS value that separates the linear and saturation regions.)
