Thyristor 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).
