This device allows current to flow only in forward direction (from the positive/drain to negative/source port). Also, it is capable to block voltage only in forward directionin both directions and can also block the voltage in both directions. Its states depends only on gate control signal (controlled commutation) and on the conditions imposed by the external circuit.

The field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current. FETs are devices with three terminals: source, gate, and drain. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source.
