A thyristor is an electronic segment that can be utilized to make a locking circuit. It is otherwise called a bistable. Like FETs, they are advanced changes that react to an information voltage. Be that as it may, not at all like FETs the thyristor will stay on regardless of whether the information voltage is expelled, enabling power to stream until the thyristor is reset. This implies they are extremely helpful in alarm circuits.
Thyristors have three leads:
- Cathode
- Anode
- Gate
At the point when the entryway leg gets a passing sign of something like 2V it switches on completely, enabling power to stream between the cathode and the anode. The present keeps on streaming until the thyristor is reset by interfering with the present move through it.
