1300860286 is a kind of electronic components called thyristor. Thyristors have the function of controlling the order and the voltage of the load, so as to protect the original equipment and achieve the best preset protection effect. They are widely used in electric power, industries, automobile control, water supply and drainage, military industry and other fields. Its working principle is divided into three stages, which are turn-on, turn-off and sustain stages.

In the turn-on stage, it needs a large current to pass through the gate electrode to form a dynamic channel on the surface of the PN junction. These channels are composed of electrons and holes. This channel can conduct the current, and the current is greatly increased in a very short time, and then the surface layer generates heat. This heats the whole electrode to quickly stabilize the hole and electron flow, and finally form a low resistance path. In the turn-off stage, the thyristor is turned off by eliminating the current path formed on the surface of the PN junction. By reducing the current of the control terminal, the channel in the dynamic state is destroyed and the current path is eliminated, resulting in a complete disconnection between the anode and the Cathode. In the sustain phase, the current flows through the electrodes quickly after the thyristor is turned on and the dynamic channel is stabilized. As long as there is current in the control terminal, the thyristor can maintain contact and play a role in current control.

In the power industry, thyristors are mainly used as current regulators and AC-DC converters. Generally, the power supply with thyristor output is called “thyristor power supply”. They are used for controlling the current and voltage of electric drive system and large power frequency converters. In the industry, thyristors are widely used in energy saving technology, electric motor speed control, motors of small and medium power variable frequency speed regulation, chemical industry temperature control, textile industry speed control. In the automobile control field, thyristors are used in the starter of gasoline engine, air pump and current sensor of vehicle, which can control the starting and working speed of gasoline engine. In the water supply and drainage field, thyristors can be used in the control of automatic water supply system, and even used to detect water leakage by measuring the current.

Thyristors have a wide range of applications and play a very important role in some fields, but its application continues to expand with the continuous advancement of technology and human needs. In summary, 1300860286 are mainly used in electric power, industries, automobile control, water supply and drainage and other fields, and its working principle is divided into three stages, which are turn-on, turn-off and sustain stages.
