SITh – Static Induction Thyristor, or FCTh – Field Controlled Thyristor – containing a gate structure that can shut down anode current flow. TRIAC – Triode for Alternating Current – A bidirectional switching device containing two thyristor structures with common gate contact See more A thyristor is a solid-state semiconductor device with four layers of alternating P- and N-type materials used for high-power applications. It acts exclusively as a bistable switch (or a latch), conducting when the gate … See more The silicon controlled rectifier (SCR) or thyristor proposed by William Shockley in 1950 and championed by Moll and others at See more TRIAC The functional drawback of a thyristor is that, like a diode, it only conducts in one direction so it can't be safely used with AC current. … See more In recent years, some manufacturers have developed thyristors using silicon carbide (SiC) as the semiconductor material. These have … See more The thyristor is a four-layered, three-terminal semiconductor device, with each layer consisting of alternating N-type or P-type material, for example P-N-P-N. The main terminals, labelled anode and cathode, are across all four layers. The control terminal, … See more Thyristors are mainly used where high currents and voltages are involved, and are often used to control alternating currents, where the change of … See more Thyristor manufacturers generally specify a region of safe firing defining acceptable levels of voltage and current for a given operating temperature.
