WebbA thyristor is a four layer, semiconductor of p-n-p-n structure with three p-n junctions. It has three terminals, the anode, cathode and the gate. The word thyristor is coined from thyratron and transistor. It was invented in the year 1957 at Bell Labs.

The main purpose of Snubber Circuit is to prevent the unwanted triggering of SCR or thyristor due to high rate of rise of voltage i.e. dv/dt. We already know that if the rate of rise of anode to cathode voltage of SCR is high then it may lead to false triggering. This is commonly known as dv/dt triggering.
