Thyristors - TRIACs are a group of semiconductor components that are composed of several alternate layers of P-N junction semiconductor materials. They are used to control high voltages and currents, mainly as switches and as limiters in power control applications. CQ202-4NS is one example of a TRIAC that is specifically designed for use in industrial and domestic power control applications.

The CQ202-4NS TRIAC is primarily used in applications where precise control of the current and voltage is required, such as in dimmer switch applications. It is a three terminal device with a Gate, Anode and Cathode. By changing the voltage or current applied to the Gate terminal, the current through the Anode and Cathode can be controlled.

The CQ202-4NS uses the Gate terminal to control the switching on of the TRIAC. When the Gate terminal is below the breakover voltage of the Anode, the TRIAC is “off” because the Anode is reverse biased. However, when the voltage at the Gate terminal is equal to or greater than the breakover voltage, the Anode is forward biased and current starts flowing through the TRIAC. This current can then be controlled by varying the voltage at the Gate.

The CQ202-4NS is specifically designed to provide low distortion of the current waveform, making it ideal for dimmer switch applications. It is also able to handle high frequency application, making it suitable for switching high-frequency power with no distortion. The CQ202-4NS has a fast switching speed and a low turn-on and turn-off time, meaning it can respond quickly to changes in the current or voltage.

The CQ202-4NS is also designed to be robust, with a low thermal resistance and excellent heat dissipation. It can operate over a wide range of temperatures and withstand high external temperatures. Additionally, its small size and low weight make it ideal for a variety of applications.

In summary, the CQ202-4NS is a three-terminal device designed for precise control of current and voltage, making it suitable for use in dimmer switch applications and other power control applications. Its fast switching time and excellent heat dissipation make it ideal for high-frequency, high-power applications, while its small size and low weight make it a great choice for a wide variety of applications.
