CQ220-12MFP

Thyristors - TRIACs

The CQ220-12MFP is a thyristor that belongs to the triac family, and it is designed for use in power switching applications. The triac family of thyristors, also known as three-terminal solid state switches, is composed of four terminals: input, output, anode, and cathode. They have the ability to control large amounts of current while also possessing rapid switching capabilities, making them ideal for switching applications.

The CQ220-12MFP is popularly used in power switching applications in a variety of industries, including automotive, power electronics, and lighting, among others. It is also used in instrumentation and test equipment. The primary advantages of using this type of thyristor include its reliable operation, low voltage drop, and excellent thermal characteristics. The CQ220-12MFP triac is also ideal for use in AC power control and motor speed control.

Working Principle

The CQ220-12MFP works by allowing current to flow through the thyristors in both directions since it is a bidirectional device. This makes it ideal for power switching applications. When the voltage is applied to the gate-cathode of the thyristor, the gate current flows and can turn it on. This is known as “firing” the thyristor. The thyristor can then be turned off either by removing the gate current or by reverse-biasing the gate-cathode. The CQ220-12MFP triac also features an isolation ring to minimize noise and ensure maximum EMC performance.

Application Field

The CQ220-12MFP triac is widely used in power switching applications in various industries. It is often used in automotive systems and power electronics for power switching applications like switching electric motors. It is also useful in instrumentation and test equipment. AC power control is one of the main applications of the thyristor, as it is designed for use in controlling the power of industrial systems as well as residential appliances. Its ability to switch rapidly makes it ideal for motor speed control.

The CQ220-12MFP is also used in lighting applications. It can be used to control LED lighting, providing the user with control over brightness, power, and color without needing to use a complicated control circuit. Additionally, it can be used in light dimming applications. It has the ability to control power without flickering or buzzing, ensuring good stability and reliability.

The CQ220-12MFP is an ideal choice for a wide range of power switching applications due to its reliable operation, low voltage drop, and excellent thermal characteristics. It is capable of controlling large amounts of current with rapid switching, making it suitable for a variety of applications in a variety of industries.
