Layer diagram of thyristor. The thyristor has three p-n junctions (serially named J 1, J 2, J 3 from the anode). When the anode is at a positive potential V AK with respect to the cathode with no voltage applied at the gate, junctions J 1 and J 3 are forward biased, while junction J 2 is reverse biased.
SCR 4-layer (p-n-p-n) diagram. A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device.The name "silicon controlled rectifier" is General Electric's trade name for a type of thyristor.

The lower p-layer works as the collector of this PNP transistor and has its voltage heightened: this p-layer also acts as the base of an NPN transistor made up by the last three layers just over the MT2 terminal, which, in turn, gets activated. Therefore, the red arrow labeled with a "3" in Figure 6 shows the final conduction path of the ...
A distributed buffer gate turn-off thyristor (DB-GTO) is a thyristor with additional PN layers in the drift region to reshape the field profile and increase the voltage blocked in the off state. Compared to a typical PNPN structure of a conventional thyristor, the DB-GTO thyristor has a PN–PN–PN structure.

Both women were known for their style and grace: Their shared appreciation for looking their best added another layer to their connection. “They were both style mavens,” Jordan notes.
Also referred to as a SYDAC (silicon thyristor for alternating current), bi-directional thyristor breakover diode, or more simply a bi-directional thyristor diode, it is technically specified as a bilateral voltage triggered switch. Its operation is similar to that of the DIAC, but a SIDAC is always a five-layer device with low-voltage drop in ...
