Description
Thyristor is a semiconductor device, belonging to the four-layer, three-connection semiconductor device series. It is an electronic switch that controls the flow of current in a circuit.
Thyristors are well known for their ability to switch high voltages and currents, making them useful in a wide range of applications including power control and electronic switching.
A thyristor is a three-terminal device, i.e., anode (A), cathode (K), gate (G), and four-layer device. The terminal connected to the outer P region is called the anode (a) and the terminal connected to the outer N region is called the cathode (k). The inner region of the P layer is connected to the terminal gate (G).
Thyristors have three modes of operation: (i) reverse blocking mode; (ii) forward blocking mode; and (iii) forward conduction mode. In the detailed mode of operation, we can see the static VI characteristics of the thyristor
5SHX2645L0004 3BHL000389P0104 is a member of the transistor family from a structural point of view. The word “thyristor” is made up of capital letters Terry Electron Accelerator Easter . Thyristors are therefore solid-state devices, similar to transistors, with thyristor-like characteristics.
The terminal characteristics of thyristors make them different from other semiconductor devices such as Diodes and transistors. The main terminals of a thyristor are the anode (A), cathode (K) and gate (G).
Anode (A):The anode is the positive terminal of the thyristor. Current enters the device when the thyristor is in its front conducting state.
Cathode The cathode is the negative terminal of the thyristor. The current exits there when the thyristor is in a conductive state in front of it.
