CQ220-6BS

Thyristors, commonly known as TRIACs, have been widely utilized in commercial and industrial applications. This is due to the variable nature of the transistor’s current carrying capacity and the ability to switch both DC and AC currents. The CQ220-6BS is a thyristor specifically designed for high power applications. It is a representative example of the many TRIACs available today. This article will provide an overview of the CQ220-6BS’s application field and working principle.

The CQ220-6BS is designed for use in applications that require high levels of power. It is capable of handling up to 2 kilo watt, making it suitable for a variety of applications. These applications include, but are not limited to, motor speed control, motor braking, static switching, light dimmers, and inrush current limiting. It is also used in appliance controls, robotic systems, and hot water heating systems.

The CQ220-6BS is a three terminal device, where the terminals are designated as the anode (A), gate (G) and cathode (K). To effectively utilize this device, the gate must be driven by negative pulses to turn on the circuit. The anode should be connected to the positive side of the power supply, while the cathode should be connected to the negative side. In terms of electrical characteristics, the CQ220-6BS has a response time of 0.2 microseconds, and a peak on-state voltage of 1.8 volts.

The CQ220-6BS’s main body consists of two AC thyristors connected back to back, creating a symmetrical circuit. The gate terminal is attached to the junction between the two thyristors, and the gate signal is used to trigger the circuit. When a positive gate signal is applied, current will flow from the anode to the cathode, and the thyristor will turn on. Conversely, when the gate signal is reversed, the thyristor will reverse its conduction direction and turn off. By adjusting the gate signal, the CQ220-6BS can be used to control the on and off times of the circuit, allowing for accurate and efficient control of power levels.

The CQ220-6BS also has a variety of protection features, such as surge current limiting, over-voltage protection, and thermal shutdown. These features help to ensure that the device is protected from excessive voltages, currents, or temperatures. Furthermore, the CQ220-6BS is designed to be robust and reliable, allowing it to function in harsh environmental conditions.

In conclusion, the CQ220-6BS is a reliable and robust thyristor designed for high power applications. Its three terminal construction allows it to switch both DC and AC currents, and its protection features provide enhanced safety in harsh environments. Its variable nature makes it suitable for a variety of applications, where its excellent response time and high power handling capabilities ensure the highest levels of performance.
