Q6008R559

Thyristors - TRIACs

The Q6008R559 is a TRIAC, a type of thyristor. A thyristor or silicon control rectifier (SCR) is an electrical component that acts as a semiconductor switch for controlling electric power. It is commonly used for light dimmers and other power switching applications, such as motor speed control and appliance control. The Q6008R559 is especially suited for AC mains dimming of low power loads, such as halogen lighting and resistive loads.

Application Field

The Q6008R559 TRIAC is specifically designed for applications where load power is no greater than 600V and the load current is no more than 8A. It can be used for light dimmers, motor speed control, and appliance control. Additionally, it can also be used in AC mains dimming of low power loads, such as halogen lighting and resistive loads. The device can also be used as a static switch in power circuits.

Working Principle

The Q6008R559 is a two-terminal, three-junction device. It is composed of two PN junctions and a third, non-linear layer of P-type material. It uses the junction of two opposite-facing silicon diodes to create a conduction channel from one side of the device to the other. A positive voltage applied to either of the two main terminals turns it on, allowing current to flow in either direction, depending on which terminal the voltage was applied to. When the voltage is removed, the conduction channel is cut and current ceases to flow.

The Q6008R559 is an isolated, low power AC switch, meaning that it is stable and not affected by temperature or environmental changes. It is also quite reliable, with a long life expectancy and low standby current draw. The device is also capable of switching frequencies up to 5 kHz, making it suitable for use in AC motor controllers.

Conclusion

The Q6008R559 is a TRIAC, a type of thyristor designed specifically for lower power applications. It is capable of switching AC loads, such as dimmers and motor speed controllers. Additionally, it is also quite stable and reliable, with a long life expectancy and low standby current draw. The device is also capable of switching frequencies up to 5 kHz, making it suitable for use in AC motor controllers.
