Thyristors - TRIACs

A TRIAC, or triode alternating current switch, is a special type of thyristor, which is a voltage-triggered, high-power, three-terminal semiconductor device, capable of controlling the phase and amplitude of the current on the output side. It has the particularity of working as a bidirectional switch, as it can conduct current in both directions, making it the ideal component for AC power control.

CQ220-10M Application Field and Working Principle

The CQ220-10M is a Bidirectional TRIAC, featuring very low on-state resistance, making it suitable for use in a wide range of applications, such as air conditioners, motors, pumps, lighting equipment and other AC inductive loads. It is capable of controlling the AC current through a range of 0 to 10 A, making it an ideal component for applications in which a low power consumption is required.

The CQ220-10M is designed to be triggered via gate current. When gate current is applied, the TRIAC is turned on and conducts the current in the direction that is determined by the polarity of the input voltage. Once the gate current is removed, the TRIAC turns off, quickly limiting the current flow through the device. This on-off triggering is used to control the amplitude and phase of current in AC applications, as it can be used to regulate the load current or switch it on or off.

The CQ220-10M is designed for operation on AC power with a maximum voltage rating of 250 VAC, a rated current of 10A and a peak current of 33 A. It has an 500V isolation rating and a typical rise time of 20 ns. Its response to turn-ori is typically 10 us at room temperature, while its operating temperature range is -20 °C to +85 °C.

In addition to its on-state current control capabilities, the CQ220-10M features several safety features that ensure the robustness and reliability of the device. It features a built-in over-temperature protection, as well as a protection against significant overloads and over-voltage. The CQ220-10M is also insulated with a high voltage insulation material, ensuring the safety of the operation.

The CQ220-10M is a versatile and reliable electronics component suitable for a variety of AC applications. It is ideal for controlling AC loads with low power consumption, making it well suited for applications in air conditioners, motors, pumps and lighting equipment. Its robust design and safety features also ensure its reliability and make it an ideal choice for engineers looking for a reliable and cost-effective solution for their AC applications.
