Thyristors - TRIACsA TRIAC is a three-terminal electronic switch made up of two transistors connected together in inverse parallel that can be used for controlling AC power. It was developed by General Electric in the 1950s and has since made its way into industrial, consumer, and commercial applications for the control of voltage and current. The BT131-800E/L01EP is a TRIAC made by NXP Semiconductors and is commonly used in motor speed control, dimmers, and light controllers.The BT131-800E/L01EP is a sensitive-gate TRIAC and is capable of being triggered by a small gate current, allowing it to be used in a variety of applications. The BT131-800E/L01EP has a voltage rating of 800V and a current rating of 4A, making it suitable for use in medium-power applications.The BT131-800E/L01EP has a number of applications, which include controlling AC motors in pumps, fans, and industrial machines, dimmers for light switches, and temperature controllers in appliances. Because the BT131-800E/L01EP is capable of operating at high frequencies, it can be used in high-speed motor control applications.The working principle of the BT131-800E/L01EP is based on the switching action of the thyristors. The BT131-800E/L01EP is a majority carrier device, meaning that the majority of the current conducted through it is carried by the majority type carriers, or holes. When the gate terminal is energized with a positive voltage, the majority carriers are attracted to the gate and a small current starts to flow through the device. This current is called the “gate current” and it causes the majority carriers to collect at the gate region and start to form a small channel between the two terminals.When this channel is created, the current flow increases exponentially and the device switches into a conducting state. The device then remains in a conducting state until the gate current is removed, which then causes the device to turn off. This switching action of the device is controlled by the gate current and is dependent on the resistance of the device and the amount of current flowing through it.The BT131-800E/L01EP is an ideal device for switching voltage and current due to its ease of use and low cost. It is capable of controlling AC motors, dimming lights and controlling temperature. Its sensitivity to gate voltage makes it possible to use it in a variety of applications and its wide voltage and current ratings make it possible to use it in a range of medium-power applications.
