CQ220I-16D

Overview

The CQ220I-16D is a Thyristor - TRIACs Device, which is a 3-terminal solid-state semiconductor device that controls the flow of electrical current in either direction. It is used as a switch or amplifier in AC circuits and as a voltage regulator.

Application Fields

• Lighting Control
• Industrial Applications
• Motor Control
• Heating Control
• Headlight Dimmer Systems
• AC Relays
• Switching Power Supplies

Working Principle

When a signal is applied at the gate terminal of the CQ220I-16D, a voltage is created that is higher than the breakdown voltage of the thyristor, the voltage will be held until the current starts to flow. When the thyristor receives the proper amount of current, it will turn on. The thyristor can then control the power that is being supplied to the load. When current stops flowing, the thyristor turns off.

The CQ220I-16D can be used in a variety of applications, from simple on-off switching of AC power, to more complex pulse-width modulation (PWM) type applications. The device can also be used in a range of industrial applications such as heating and lighting control, motor control, and AC relays.

Conclusion

In conclusion, the CQ220I-16D is a Thyristor – TRIACs device that can be used in various application areas, from simple on-off switching of AC power to more complex applications. The device is capable of controlling the flow of electrical current in either direction and is used as a switch or amplifier in AC circuits, as well as a voltage regulator.
