Thyristors-TRIACs include a wide range of semiconductor devices used to control current in an alternating current (AC) circuit. A TRIAC is an abbreviation for Triode for Alternating Current and is a three terminal electronic component that is widely used in industrial, commercial, and residential electrical systems. The QK016RH6 is a popular TRIAC device used in a variety of applications, and this article will examine the application field and working principle of this device.

Application Field

The QK016RH6 TRIAC is a low-cost, low-power, medium-current device that is suitable for a wide range of applications, including lighting and heating control, motor control, and general AC switching. The device is available in a range of packages and with a minimum breakdown voltage of 16V. This makes it suitable for applications with supply voltages of up to 250V AC.

The device is widely used in a variety of applications due to its ability to control AC loads with a high degree of accuracy and repeatability. For example, it is used in lighting control systems to regulate the intensity of incandescent and fluorescent lighting, and in motor control systems to precisely adjust the speed of a motor. In addition, the device is suitable for a wide range of industrial and commercial equipment, including air conditioners, vending machines, and small household appliances.

Working Principle

The basic operation of the QK016RH6 TRIAC is similar to that of a MOSFET, and it can be used to switch an AC load at a predetermined set point. However, unlike a MOSFET, the TRIAC has two "gates" which can be used to control the current flow in either direction. When a signal is applied to the gate(s) of the device, it will turn "on" and allow current to flow through the load connected to it.

The device is turned off by removing the signal from the gate and the current flowing through it will return to zero. Due to the nature of AC circuits, the device will then turn "off" when the current changes direction and return to zero again. This process is repeated each time the signal is applied to the gate of the device.

The QK016RH6 can be used to accurately control the current flowing through a load by varying the signal that is applied to it. This allows the device to be used for applications such as motor speed control and lighting intensity control. In addition, the device is capable of switching high currents quickly and reliably, making it suitable for a wide range of applications.

Conclusion

The QK016RH6 TRIAC is a versatile, low-cost, low-power device that is capable of controlling AC loads with a high degree of accuracy and repeatability. It is suitable for a wide range of applications, including lighting and heating control, motor control, and general AC switching. The device is turned on and off by varying the signal that is applied to its two gates, allowing it to be used for applications such as motor speed control and lighting intensity control.
