A DIAC is a device which has two electrodes, and …
WebA thyristor is a 4 layer bipolar current controlled device having 3 terminals. A thyristor is basically designed to conduct a large current when it is on and block high voltage when it is in the off state. This means they can be switched on whenever there will be an appropriate control signal present at the gate terminal of the thyristor.
