Thyristor - Wikipedia
A thyristor (/ θ aɪ ˈ r ɪ s t ər /) is a solid-state semiconductor device with four layers of alternating P-and N-type materials. It acts exclusively as a bistable switch, conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed (by some other means).
