The TN805-800B is a type of semiconductor controlled rectifier device which is more commonly known as a thyristor. It is also known as an SCR, or silicon controlled rectifier, due to its unique ability to control the flow of electrical current. The TN805-800B has a wide variety of applications and is widely used in industrial, commercial and consumer applications.

The TN805-800B is a four layer thyristor which is made up of an anode, a gate, and two cathodes. The anode is the positive terminal, the gate is the control terminal, and the cathodes are the negative terminals. The TN805-800B is usually connected in series, as this allows it to be controlled by a single gate voltage. This thyristor also has a maximum peak repetitive reverse blocking voltage of 800V and a maximum average surge current of 40A.

A thyristor works on the principle of the three-state switching action. It is essentially a two-way switch, which can switch from a conducting to a non-conducting state. When the voltage across the gate and cathode is positive, the thyristor will be in a conducting state. When the voltage is zero, the thyristor will be in a non-conductive state. The TN805-800B can be used for either AC or DC control, depending on the application.

The TN805-800B is an ideal choice for applications requiring bidirectional control of large currents. It is often used in AC motor control, induction heating systems, dimmers, starters and lighting systems. It is also suitable for use in motor control applications such as speed control of AC motors, as well as synchronous motor, hoist, and crane control. The TN805-800B is also used in applications where high current is required, such as welders and battery chargers.

The TN805-800B is a high voltage thyristor which is capable of controlling larger currents than standard thyristors. Its high blocking voltage makes it suitable for a wide variety of applications, as it can withstand high in-rush currents. It is also designed to provide maximum switching speed, so it can switch rapidly between states and provide precise control of current. This makes it particularly suitable for applications where fast control of large currents is required.

In conclusion, the TN805-800B is a powerful four layer thyristor which offers a wide range of applications and can provide precise and rapid control of large currents. Due to its high blocking voltage and fast switching speed, it is well-suited for a number of industrial, commercial, and consumer operations. It is ideal for use in AC motor control, induction heating systems, dimmers, starters and lighting systems, as well as for welders, battery chargers and other high current applications.
