bidirectional trigger diode

The bidirectional triggering diode came out at the same time as the bidirectional thyristor and is often used to trigger the bidirectional thyristor. Related pictures on this topic are as follows: In addition to being used to trigger bidirectional thyristors, bidirectional trigger diodes are also commonly used in overvoltage protection, timing, phase shifting and other circuits. Figure 2 is an overvoltage protection circuit composed of a bidirectional trigger diode and a bidirectional thyristor. When the transient voltage exceeds DIAC and Ubo, DIAC quickly turns on and triggers the triac to also turn on, protecting the subsequent load from overvoltage damage.
