Thyristors - TRIACs

A Triac (short for Triangle AC) is a type of thyristor, or a semiconductor device similar to a diode that can be triggered to conduct current via a positive or negative voltage. The triac is commonly used in applications that require both AC and DC power for a switch or a motor, such as dimmer switches for lights.

The BTA216-800B,127 is a type of triac that is used in applications that require high current control across a wide range of temperatures. This type of triac has a high on-state current and peak current ratings, as well as a low turn-off time. The triac also has a low thermal resistance and is capable of carrying current up to 800A DC or 600A AC.

Application Field

The BTA216-800B,127 is typically used in appliances, instruments, and control systems. Common applications include motor control, lighting control, motor speed control, solar inverters, and dimmer switches.

Working Principle

The working principle of the BTA216-800B,127 is based on the principle of a four-layer oxidation technology, wherein the front and rear contacts are linked through two layers of silicon. The power flow is managed between these two layers, with the front contact providing the current to the rear contact. This allows a low switching threshold voltage, which helps reduce power consumption. The triac\'s gate control allows the current to be switched on and off, with the gate being able to be triggered through a positive or negative voltage.

In addition, the triac has a very fast switching time and is able to handle high peak currents, making it highly efficient in its current control applications. It also has a low thermal resistance, allowing increased heat dissipation and greater power handling capability. The triac is also rated for reverse power dissipation, which helps reduce any potential damage from overload or short-circuiting. Lastly, the device is easy to integrate into various control system applications and is available in a variety of packages to suit different applications.
