BT131-800D,412

Thyristors are a type of semiconductor device that is triggered when forward bias voltage is applied to the gate junction. TRIACs, or triode for alternating current, are thyristors that have three terminals – cathode, gate and anode. The BT131-800D,412 is a type of TRIAC that is widely used for switching AC current. This article will explain the application field and working principle of the BT131-800D,412.

Applications

The BT131-800D,412 is a Bidirectional Triode Thyristor that can be used in a variety of AC switching applications. It is commonly used in AC current control applications due to its ability to withstand high currents. It is commonly found in small motors, light dimmers, solenoid valves, heating systems and other household appliances.

The BT131-800D,412 is also useful in AC power transmission systems, where it can be used to control high power levels. It can be used in dynamic braking systems, power rectifiers and some types of welding equipment. It is also suitable for use in DC motor control systems.

Working Principle

The BT131-800D,412 is a solid state, three terminal device. It operates by triggering a flow of current when a predetermined forward bias voltage is applied to its gate junction. The device is designed to allow a certain amount of current to flow through it in either direction, depending on whether the voltage is positive or negative. When the voltage is positive, the device switches on and allows a current to flow from the anode to the cathode. When the voltage is negative, the device switches off and prevents current from passing through the device.

The device controls the current flow by controlling the voltage at the gate junction. When the voltage is increased, more current is allowed to pass through the device, whereas when the voltage is decreased, the amount of current allowed to pass through is reduced. The device is capable of controlling both high and low power levels with precision and accuracy.

The BT131-800D,412 is capable of withstanding temperatures of up to 125 ˚C and is also resistant to shock and vibration. It is designed for use in environments where noise levels are low, and its dimensions are suitable for use in a variety of applications.

In summary, the BT131-800D,412 is a type of TRIAC that is widely used for AC current control. It is used in a variety of applications, including small motors, light dimmers, solenoid valves, heating systems and power transmission systems. It operates by controlling the current that passes through the device by controlling the voltage at its gate junction. The device is capable of withstanding temperatures of up to 125 ˚C and is resistant to shock and vibration. It is suitable for use in environments where noise levels are low.
