BTA201-800ER,126

Thyristors - TRIACs

A triac is a three-terminal electronic component that combines the functions of a thyristor and a diode. It acts as a bidirectional switch, and is commonly used to control AC power in a variety of applications. TRIACs are a special type of thyristor, used to control the flow of current from an AC source. The BTA201-800ER,126 is a wide-range, high-power thyristor designed to operate at temperatures up to 125 degrees Celsius.

Design and Operation

The BTA201-800ER,126 is a 4-layer, symmetrical thyristor with two terminals, termed gate and anode. The two anode terminals are connected to the two main supply lines, while the gate terminal is linked to a DC power source. As the gate voltage is increased, the TRIAC gradually begin to conduct current in both directions, providing efficient control of AC power over a wide range of operating conditions. The device includes a high-temperature gate drive, high-temperature baseplate, and low-power losses for improved efficiency and energy savings.

Advantages

The BTA201-800ER,126 offers several advantages over other types of thyristors. It provides a wide voltage and current range, allowing it to operate in a variety of applications requiring a high amount of power. The device also has high thermal stability and improved pulse current capability, which allows for efficient control of current in various applications. Furthermore, its integrated design ensures easy installation, making it ideal for many AC control applications.
