Thyristors are a class of semiconductor components that are used in power control and switching applications. A TRIAC is a type of Thyristor that uses two sections, one on each side of an emitter terminal. The CQ220-12D is a TRIAC that is specially designed for high current applications. In this article, we will discuss the application field and working principle of the CQ220-12D.

The CQ220-12D has been designed for power switching in LED lighting systems, heating systems, and other power control applications. The TRIAC is rated for up to 12 amperes of load current and is designed to handle up to 300 volts. It has a turn-off time of less than 10 microseconds which allows for fast switching. In addition, it has a reverse-recovery spring mechanism which helps to reduce EMI disturbance and makes it suitable for operation in industrial control systems and communications systems.

The working principle of the CQ220-12D is based on the use of two gates, one on the Anode side and one on the Cathode side. The Anode gate is the input to the TRIAC and is used to control the current flow. It is connected to the emitter of the TRIAC and is used to turn on and off the circuit. The Cathode gate is used to control the turn-off time of the TRIAC. It is connected to the Collector of the TRIAC and is used to control the time taken to turn off the circuit.

When the Anode gate is in the ON state, current flows from the Anode side to the Cathode side of the TRIAC and the current is determined by the resistance of the load. This is known as the Forward-Bias condition. When the Cathode gate is in the ON state, a buildup of electric charge occurs at the Cathode side and the current flow is stopped. This is known as the Reverse-Bias condition and is used to turn off the TRIAC. The turn-off time of the TRIAC is determined by the charge stored at the Cathode side.

The CQ220-12D has a wide range of applications and is suitable for many power control and switching applications. It has been designed to handle up to 12 amperes of load current and is rated for up to 300 volts. In addition, it has a low turn-off time of less than 10 microseconds which makes it suitable for applications where quick response and high reliability are required. Finally, it has a reverse recovery spring mechanism which helps to reduce EMI disturbance.
