Web22 sep. 2024 · A Field Effect Transistor (FET) is a three-terminal Active semiconductor device, where the output current is controlled by an electric field generated by the input voltage. FETs are also known as unipolar transistors because, unlike bipolar transistors, FETs only have either electrons or holes operating as charge carriers. Web12 aug. 2015 · JFETs are depletion-mode devices (P- and N-channel alike). This means that with no gate-source voltage applied the channel is already formed and it can conduct current. In this latter situation (Vgs=0) the current is called I D S S in datasheets, and it is (practically) the maximum current your device can handle.
