JFET (Junction Field-Effect Transistor) – N-CHANNEL or P-CHANNEL Electrovo -
The junction gate field-effect transistor (JFET or JUGFET) is one of the simple type of field-effect transistor.[1] JFETs are three-terminal semiconductor devices that can be used as electronically-controlled switches, amplifiers, or voltage-controlled resistors. Unlike bipolar transistors, JFETs are exclusively voltage-controlled in that they do not need a biasing current. Electric charge flows through a semiconducting channel between source and drain terminals. By applying a reverse bias voltage to a gate terminal, the channel…
