Thyristors are in stock at Tenco Electronics.A thyristor is a solid-state semiconductor device with four layers of alternating N and P-type materials. It acts exclusively as a bistable switch, conducting when the gate receives a current trigger, and continuing to conduct while the voltage across the device is not reversed (forward-biased). Tenco offers inventory, pricing, & datasheets for thyristor . To know more, please view our large section of Circuit Protection -TVS - Thyristors below.
