![]() ![]() A JFET is usually conducting when there is zero voltage between its gate and source terminals. By applying a reverse bias voltage to a gate terminal, the channel is pinched, so that the electric current is impeded or switched off completely. Electric charge flows through a semiconducting channel between source and drain terminals. Unlike bipolar junction transistors, JFETs are exclusively voltage-controlled in that they do not need a biasing current. JFETs are three-terminal semiconductor devices that can be used as electronically controlled switches or resistors, or to build amplifiers. The junction-gate field-effect transistor ( JFET) is one of the simplest types of field-effect transistor. *This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.Electric current from source to drain in a p-channel JFET is restricted when a voltage is applied to the gate.
