Thyristors - TRIACs

A TRIAC is a three-terminal semiconductor device, which is part of the family of thyristors. The acronym TRIAC stands for Triode for Alternating Current, and is classified as an AC switch. TRIACs are controllable three terminal bi-directional switches, which can be triggered by a current or voltage applied to the main terminal, or Gate.

The CQ220I-8N is a popular TRIAC that is often used in such applications as AC motor controls, dimmer controls, welding equipment, and industrial heating. It has a turn-on voltage of 800V and a current rating of up to 8A.

The CQ220I-8N works by breaking up the AC waveform and turning on at a specific angle determined by the applied Gate voltage. When a positive voltage is applied to the Gate, the TRIAC turns on and provides a low resistance path between the Anode and Cathode, allowing current to flow. This process is known as triggering, as it is triggered by the applied voltage. When the Gate voltage is removed, the TRIAC will turn off and prevent any further current flow.

The CQ220I-8N can be used to control the amount of current flowing through an AC circuit. In AC motor controls, for example, the TRIAC can be used to vary the amount of power delivered to the load without the need for a bulky and expensive phase control circuit. Other applications include phase-angle control of AC power in products such as light dimmers, temperature controllers, and thermostats.

The CQ220I-8N is a robust and reliable TRIAC that can handle a wide range of applications. It is also cost-effective, making it a popular choice for commercial, industrial, and DIY applications.
