WebA Thyristor is a unidirectional semiconductor solid state device with four layers of alternating P and N type material. It consist of three electrodes i.e. Anode, Cathode and a Gate. Anode is the positive terminal and Cathode is the negative terminal. The Gate controls the flow of current between anode and cathode. WebJun 13, 2015 · Structural view of thyristor . N-base is a high-resistivity region and its thickness is directly dependent on the forward blocking rating of the thyristor. But more width of the n-base indicates a slow response time for switching. The symbol of the thyristor is given in Figure 35. Figure 35. Schematic symbol of thyristor . Figure 36.

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.
