Dongguan 2016 Houjie Electrical Circuit Breaker teaches you how to use it for training

The abbreviation of electrostatic induction thyristor is obtained by adding an emitter layer with a conductivity type different from that of the drain layer on the drain layer. Because its working principle is similar to that both the gate and anode voltage can control the anode current through the electric field, it is also called a field-controlled thyristor (). Compared with the bipolar device, which has an additional junction with minority carrier injection function and is a two-carrier conductive device, it has a conductance modulation effect that reduces the on-state voltage and has strong current flow capability. Many of its characteristics are similar to those of the other two but with a higher switching speed ratio
