Structure on the physical and electronic level, and the thyristor symbol. Thyristors have three states: Reverse blocking mode – Voltage is applied in the direction that would be blocked by a diode Forward blocking mode – Voltage is applied in the direction that would cause a diode to conduct,...
It was created to take the position of GTO. Fig 10. MOS Turn-off Thyristor Symbol It is a latching device that works better in terms of power and blocking voltages than MCT and IGBT. It was created by Silicon Power Company (SPCO), and functions similarly to the GTO, but it also has ...
The DIAC circuit symbol is generated from the two triangles held between two lines as shown. In some way this demonstrates the structure of the device which can be considered also as two junctions. The two terminals of the device are normally designated either Anode 1 and Anode 2 or Main Te...
The silicon controlled rectifier, SCR or thyristor symbol used for circuit diagrams or circuit seeks to emphasis its rectifier characteristics while also showing the control gate. As a result the thyristor symbol shows the traditional diode symbol with a control gate entering near the junction. ...
As can be imagined from its circuit symbol shown below, the device is a "one way device" giving rise to the GE name of silicon controlled rectifier. Therefore when the device is used with AC, it will only conduct for a maximum of half the cycle. ...

Thyristor or SCR circuit symbol Note on Thyristor Technology: Thyristors or SCRs are based around a unique structure of a PNPN structure and have three electrodes: anode, cathode and the gate. When the gate receives a triggering current, it fires the thyristor enabling current to flow ...
(G) because the current flow through this device is controlled by the electrical signals applied to the gate terminal. The power terminals of this device are anode and cathode which can handle the high voltage and conduct the major current through the thyristor. The symbol of the thyristor is...
