The thyristor is a four-layered, three terminal semiconductor device, with each layer consisting of alternately N-type or P-type material, for example P-N-P-N.n earlier gas filled tube device called a thyratron provided a similar electronic switching capability, where a small control voltage could switch a large current. It is from a combination of thyratron and  transistor  that the term thyristor is derived.
Best Answer: the tricuspid (i.e. 3 cusped) valve.... It is called the tricuspid valve. Although more recent text books are now calling it the right atrioventricular valve, or Right AV valve for short. The new name tends to be more descriptive then tricuspid.
