BT131-800,116

Thyristors, popularly known as “silicon controlled rectifiers” are an important type of semiconductor devices used extensively in the switching and power control of circuits. TRIACs, a four layer, three terminal thyristor device, have the capability to control the phase angle of an AC voltage. The BT131-800,116 is a type of TRIAC that is suitable for a wide range of applications, providing excellent performance and long life.

Applications

The BT131-800,116 is a low-tolerance TRIAC designed for wide operating range applications with a high power handling capability. It is well suited for industrial automation and control applications, such as the control of motor speed, voltage regulators, and solid state relays. Besides, it can be employed in power control systems, heaters, lighting systems, and household appliances, such as washing machines and refrigerators. In addition, BT131-800,116 TRIACs can be used for larger power applications, such as hot water heaters, dishwashers, and air conditioning systems.

Working principle

The BT131-800,116 has three main terminals, labeled “gate”, “main” and “auxiliary”. The main terminals control the ON/OFF switching of the TRIAC, while the Gate is used to control the conduction of the current. The Gate terminal is connected to a power controller that acts as a switch, sending a signal to start the conduction of the current or to shut it off. The Auxiliary terminal is connected to the positive AC power line and provides a voltage reference point.

The BT131-800,116 works in the following manner. When it is turned on, the Gate receives a signal, which initiates the conduction of current through the two main terminals. The Gate terminal is connected to a power control device, such as a variable resistor, which then controls the flow of current. As the Gate input is adjusted, the current through the two main terminals will adjust accordingly. When the Gate voltage reaches a certain cut-off voltage, the conduction of the TRIAC is stopped and the circuit is switched off.

Conclusion

The BT131-800,116 is a versatile TRIAC that can be used in a variety of applications. It has the capability to control the phase angle of an AC voltage, making it an ideal choice for industrial automation and control applications. It is easy to install and operate, featuring a wide operating range and a high power handling capability. In conclusion, the BT131-800,116 TRIAC is a reliable and robust device suitable for a wide range of applications.
