Introduction

Thyristors are semiconductors that are widely used to control and regulate AC electrical power. Thyristors are a type of power electronics switch, and TRIACs are a type of thyristor. The CQ220I-16B is a TRIAC, and it is widely used in the industrial and commercial markets. In this article, we will discuss the application field and working principle of the CQ220I-16B.

Application Field

The CQ220I-16B is a medium voltage TRIAC with a 16A rating, and it is widely used in AC switching, motor control, load switching, lighting control and other industrial and commercial applications. It is also suitable for use in both domestic and commercial environment.The CQ220I-16B is an ideal choice for a wide range of applications, such as:* AC switching* Motor control* Load switching* Lighting control* Industrial and commercial applications

Working Principle

The CQ220I-16B is a three-terminal device which consists of three thyristors in a bidirectional arrangement. It is constructed with an anode, a gate and a cathode. The anode and gate are connected to the phase of the AC power source, whereas the cathode is connected to the load. When AC power is applied to the anode and gate, the flow of current is alternately blocked and allowed through the device. This process is known as phase control, and the CQ220I-16B is designed to deliver a continuous or "full-wave" current to the load. The CQ220I-16B is also designed with a maximum peak current rating of 16A, and a surge current rating of 8A. This enables it to handle higher current surges, making it suitable for applications such as motor control and load switching.

Conclusion

The CQ220I-16B is a medium voltage TRIAC with a 16A rating, and it is widely used in AC switching, motor control, load switching, lighting control and other industrial and commercial applications. Its working principle involves alternately allowing and blocking the flow of current through its three thyristors in a bidirectional arrangement. It has a maximum peak current rating of 16A, and a surge current rating of 8A, making it suitable for applications such as motor control and load switching.
