Thyristors - TRIACs

Thyristors are a semiconductor device composed of four layers of alternating P and N type material. They are widely used for controlling and switching electronic circuits. As one of the most widely used thyristors, TRIACs (Triode for Alternating Current) are widely adopted in many applications including lighting and motor control, power supplies, and power switching.

BTA312B-600E,118 Application Field and Working Principle

BTA312B-600E,118 is one of the most popular TRIACs that has a very wide application field. This device is mainly used for controlling low-power AC devices. It is often used in dimmers and light switches in home lighting applications as well as in industrial and commercial power switching applications. Furthermore, BTA312B-600E,118 can also be applied in AC motor speed controlling and low-power light dimming applications.

The product’s working principle is quite simple. It switches on the AC line allowing the current flow when a current of a certain magnitude is given to its Gate electrode. The trip current of this device is 600mA and it is able to cycle between on and off state with a repetitive rate of up to 500Hz. When the current going through the device is lower than the trip current, it allows the current flow to pass through with little resistance. When the current is higher than the trip current, the device is completely on, allowing the full current to flow through.

Summary

BTA312B-600E,118 is one of the most popular TRIACs available and has a very wide application field. This device is mainly used for controlling low-power AC devices and can be applied in AC motor speed controlling, light dimming and other low-power applications. In normal operation, it switches on the AC line allowing the current flow when a current of a certain magnitude is given to its Gate electrode. The trip current of this device is 600mA and it is able to cycle between on and off state with a repetitive rate of up to 500Hz.
