In the experiments, therefore, you use two different thyristors which seem oversized, but generally are readily available.
Roughly speaking, thyristors come in two versions...
This term is derived from the internal structure. In the course of the experiments you come back to this.
In addition, there exists a combination of a p- and n-gate thyristor.
The C-106 is a p-gate thyristor with connectors. The connectors are denominated cathode (C), anode (A) and gate (G). In the picture, the C 106 thyristor is shown with the assignment of the connectors.
