Thyristors - TRIACs

TRIACs, also known as Quadracs, are a type of transistor that utilizes symmetrical power control. TRIACs were invented in 1957 and can be used in a variety of applications such as motors, lighting, and heaters. In an AC circuit the TRIAC can be used to control the voltage passing through, allowing for better power usage efficiency.

The Q4N4RP is a four-quadrant silicon-controlled rectifier that is designed to control power in an AC circuit by regulating voltage and current flow. It is capable of reliably controlling current up to 100 amps, and is designed to have a wide range of operating temperature from -40°C to 75°C.

The Q4N4RP works by utilizing the opto-optical principle. A special photo-sensitive element senses the current flowing through the TRIAC and sends a signal to the device to adjust the voltage in an AC circuit. The voltage adjustment is made by changing the bias voltage of the TRIAC, which has the effect of changing the amount of current flowing through it.

The main applications of the Q4N4RP are in the switching and control of AC motors, lighting, and heaters. By controlling the voltage, the current flow can be regulated to provide a smoother and more efficient operation. The device can also be used for controlling the temperature of certain types of equipment and controlling the speed of AC motors.

The working principle of the Q4N4RP is based on the opto-optical principle. The device senses the current flow through the TRIAC and then sends a signal to the device to adjust the voltage in the AC circuit. This adjustment is made by changing the bias voltage of the TRIAC, which has the effect of controlling the amount of current flowing through it. By changing the bias voltage of the TRIAC, the current is either increased or decreased, depending on the applied voltage.

In addition to controlling voltage and current flow, the Q4N4RP can also be used for various safety applications, such as overload protection and short circuit protection, as well as for thermal overload protection.

The Q4N4RP provides reliable and efficient power control in a variety of applications, from motors and lighting to heaters and temperature controllers. Its opto-optical principle ensures that the current flowing through the device is accurately and reliably regulated, making it a valuable tool for controlling and managing power in AC circuits.
