How to Evaluate Pinch off Voltage of FET?

Pinch off Voltage of FET evaluator uses Pinch OFF Voltage = Pinch OFF Drain Source Voltage FET-Drain Source Voltage FET to evaluate the Pinch OFF Voltage, Pinch off Voltage of FET is the voltage at which the channel of the FET is pinched off, preventing further current flow. It is also known as the threshold voltage. In a junction field-effect transistor (JFET), the pinch-off voltage is the voltage at which the depletion regions of the gate junctions meet and pinch off the channel. This happens because the gate voltage creates an electric field that attracts electrons away from the channel, forming depletion regions. When the depletion regions meet, they effectively close the channel, preventing any further current flow. Pinch OFF Voltage is denoted by V_off(fet) symbol.
