Thyristor Electronic Component Symbol

This schematic representation illustrates the symbol for a thyristor, a fundamental electronic component used extensively in power control circuits. The symbol typically depicts a three-terminal device, featuring an anode, cathode, and a distinct gate. It resembles a diode but with the crucial addition of the gate terminal, which enables controlled conduction. When a current pulse is applied to the gate, the thyristor is triggered into a conducting state, allowing current to flow from anode to cathode until the current falls below a holding threshold or is reverse-biased. This unique switching capability makes thyristors indispensable for applications such as AC power control, motor speed regulation, and high-power switching.
