Thyristors, also called thyristor-controlled transistors (TRIACs), are semiconductor devices that are used as switches to control electrical current flow in a circuit. The BT139B-800F,118 thyristors are designed to control a variety of applications, including lighting, motor power, lamp dimmer switching, and home appliance applications such as coffee maker, washing machine, and dishwasher.

The main components of a thyristor are the main body, gate, emitter, and collector. The main body is basically a diode that can convert AC or DC power into a controlled electrical current. It is basically a one-way switch that allows current to flow in one direction. The gate is basically a control switch that is used to control the amount of current flow in the circuit. It is also used to turn the thyristor on and off.

The emitter of the BT139B-800F,118 thyristor contains two layers of PN junction elements with different conductivities. It acts as an intermediate between the main body and the collector. The collector is the output element which will allow the current to flow in a specified direction.

The BT139B-800F,118 thyristor works by controlling the flow of current between the main body and the collector. It does this by using the emitter and the gate as control switches. When the emitter is connected to the main body, it will allow the electrical current to pass through it. At the same time, the gate is used to turn the thyristor on and off. When the gate is turned on, it will cause a high voltage to be applied to the main body, which causes the current to flow to the collector. On the other hand, when the gate is turned off, it will cause a low voltage to be applied to the main body, which prevents the current from flowing to the collector.

The BT139B-800F,118 thyristor is used in a variety of applications, such as controlling the speed of motors, dimming lights, and controlling home appliances. It is also used in power supplies, such as TV and computer power supplies, and in audio amplifiers. The thyristors have the advantage of being able to control the power output without adding additional components such as resistors, capacitors, and transistors. Additionally, the thyristors are very reliable and inexpensive, making them an ideal choice for a variety of applications.

In conclusion, the BT139B-800F,118 thyristors are used to control the flow of current in a variety of applications. They work by using the emitter, gate, and collector as control switches. They are reliable, inexpensive, and can be used for controlling motors, dimming lights, and controlling home appliances. Additionally, they can be used in power supplies and audio amplifiers, making them a great choice for a variety of applications.
