What is the structure of a thyristor? What are the characteristics?

Thyristor (Thyristor) is a semiconductor device and a switching tube, which is widely used as a switch in power electronic systems. A thyristor is a triode made of n-type silicon semiconductor with three electrodes: anode, cathode and gate.

The structure of the  thyristor includes a substrate of n-type silicon semiconductor, an enhancement type of n+-type silicon semiconductor, and a junction of p-type silicon semiconductor. A p-n junction is made on the substrate of an n-type silicon semiconductor, and a layer of n+-type silicon semiconductor is coated on one side of the p-n junction to form an n-p-n structure. Applying an appropriate voltage on the control electrode can trigger the thyristor to conduct.

 thyristor have the following characteristics:

Controllability: The  thyristor can control its conduction degree, and can adjust its conduction degree by applying an appropriate voltage to the control electrode.

Triggerability: The thyristor can be triggered at a lower voltage, that is, the trigger voltage is relatively low.

High-frequency characteristics: Thyristors can work at high frequencies, and their switching speeds are very fast, and they can work at frequencies of hundreds of KHz.

Reverse Saturation Voltage: Thyristors have a very high reverse saturation voltage and can withstand reverse voltage.

Voltage resistance: The  thyristor has a relatively high withstand voltage and can withstand higher voltages.

Switching characteristics: The thyristor can be used as a switching tube and can work in the switching state.

Stability: The thyristor has good stability and will not be damaged due to factors such as overvoltage or overcurrent.

After reading the above, you should be very clear about " thyristor". If you need to know the specific product model, please leave a message for consultation.
