Thyristor - Wikipedia
https://en.wikipedia.org/wiki/Thyristor
WEBThe 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, called the gate, is attached to p-type material near the cathode.
