Thyristors are a type of semiconductor, and a TRIAC is a type of three-terminal thyristor that is specifically designed for AC applications. The CQ220-10D is a type of thyristor that is constructed from silicon and has three layers of anode and cathode. The CQ220-10D is ideal for applications where waveform control and high-reliability operation is needed with a wide range of AC and DC power supplies. This makes them a great choice for applications involving switchmode power supplies, motion control, and communication relays.

The CQ220-10D works by utilizing a controlled gate current to turn on, maintain conduction, and then turn off the output state of the device. This is accomplished by allowing a controlled gate current to flow and create a voltage across the gate-cathode junction. Once this junction is forward biased, it allows current to begin flowing and a stable conduction state is developed. This state will remain steady until the gate current is rejected and the voltage across the gate-anode junction is reversed. This will then turn-off the device.

The CQ220-10D has a very low on-state current, compared to other types of thyristors. This means that it offers high power efficiency in applications where low levels of power are required. Additionally, when powered from a mains AC supply, the CQ220-10D provides excellent harmonic characteristics, making them suitable for reducing the harmonic content of AC signals. The CQ220-10D can also be pulsed with high-frequency rectified AC, allowing for applications such as motor speed control or frequency control.

The CQ220-10D can be used in a wide range of applications, including those involving high-reliability operation, power factor correction, power switching and surge suppression. Additionally, it can be used in AC and DC electronic ballast applications, such as fluorescent lamp control, electronic transformer systems, and dimmers. The CQ220-10D also finds application in AC and DC motor controls, digital circuits, and more.

In summary, the CQ220-10D is a three-terminal thyristor specifically designed for AC applications. It offers high power efficiency and excellent harmonic characteristics, making it ideal for applications such as motor speed control or frequency control. Additionally, it can be used in a wide range of other applications, including those involving high-reliability operation, power factor correction, power switching and surge suppression. The CQ220-10D is a great choice for power supplies, motion control, and communication relays.
