Thyristors, like TRIACs, are special types of semiconductors. A TRIAC (Triode for Alternating Current) will allow current to flow in both directions and it is essentially two SCRs (Silicon Controlled Rectifiers) connected in an inverse parallel arrangement. A CQ220-16B is a special type of TRIAC and can be used for various applications. This article will discuss the application fields and the working principle of the CQ220-16B.

Application Fields

The CQ220-16B is a fast switching TRIAC, which can be used in a variety of applications. It is widely used in controlling and regulating the power supply for motor drives, heaters, lights, and other electrical loads. It can also be used for controlling hot water tanks as it has a breakdown voltage of 16 volts.

The CQ220-16B is also commonly used in home appliances like washing machines and dishwashers. It is often used to control the speed and power of motors. It is also used in audio and video equipment, including DVD players and home theatre systems.

The CQ220-16B is an ideal choice for regulating power and controlling the flow of current in various types of equipment. It is also used in industrial devices and applications.

Working Principle

The CQ220-16B works on the principle of TRIAC (Triode for Alternating Current). When a current is applied to the main gate, it generates a voltage across the main gate, which in turn leads to the release of electrons from the base region of the TRIAC. These electrons then create a conduction path for the flow of current. As the current passes through the TRIAC, it controls the flow of alternating current.

In order to control the flow of current, the gate voltage must be adjusted accurately. The gate voltage should be set at a level which will allow a certain amount of current to flow across the TRIAC without causing any damage. This voltage level is known as the “Holding Voltage” or the “Minimum On Voltage”.

The CQ220-16B can also be used to control the speed or power of motors or other loads in a circuit. By controlling the amount of current flowing through the TRIAC, the speed or power of the motor can be adjusted. This is done by adjusting the level of the Holding Voltage.

In summary, the CQ220-16B is a fast-switching TRIAC which is used in a variety of applications. It is ideal for controlling and regulating the power supply of motors and other electrical loads. It works on the principle of TRIAC and its gate voltage must be adjusted accurately in order to control the flow of current. The CQ220-16B is a reliable and effective tool for controlling the speed or power of motors and other loads.
