Bidirectional thyristor

Bidirectional thyristor is made of N-P-N-P-N five-layer semi-conductive material, and also has three electrodes.

The bidirectional thyristor is the same as a one-way thyristor, and also has the trigger control characteristic. However, its trigger control characteristics are quite different from that of a one-way diode, that is, the polarity of the voltage between the anode and the cathode, a bidirectional thyristor can be turned on as long as a trigger pulse is added to its gate, and no matter what polarity the pulse is. Because the bidirectional thyristor can realize the trigger control at the working voltage of any polarity of the anode and the cathode, the main electrode of the bidirectional thyristor has no anode the two main electrodes are called the T1 and T2 electrodes, and the main electrode on the P-type semiconductor material is called the T1 electrode, an electrode connected to the N-type semiconductor material is called a T2 electrode.

Gate turn-off ( GTO ) thyristor

Gate turn-off ( GTO ) thyristor also belongs to PNPN four-layer three-terminal structure, its equivalent circuit is the same as ordinary thyristor.

The gate turn-off thyristor is also called gated thyristor, or VS.

When the thyristor is turned on, the trigger signal is removed, and the thyristor will maintain the on-state. The characteristic of the gate turn-off thyristor is that the thyristor can be turned off automatically when the gate is plus negative trigger signal, which not only keeps the gate flow energy of the thyristor to control the large current the utility model also has the ability of controllable turn-off, which provides a convenient and wider range for the application of thyristors.
