Thyristors – TRIACs are semiconductor devices that are used for controlling current flow within circuits. The Q8010LH5 is a type of thyristor, more specifically, a TRIAC. This device has several important applications in a range of electronic circuits, as well as an interesting working principle, which will be explored in the sections below.

Application Fields

The Q8010LH5 is primarily used in solid state AC switching circuits, such as those in lighting dimmers, motor speed controllers, and various other applications. The device allows for precise control of AC power in appliances, allowing users to adjust the level of power to achieve desired results. The device is highly reliable and is perfect for use in applications that require an ultra-fast switching speed.

In addition to its use in AC switching, the Q8010LH5 can also be used in AC phase control applications. This allows the user to control the current flow in the circuit, making it possible to adjust the phase angle of the pulsating AC voltage. This is most often seen in motor speed controllers, where it is used to provide a smooth start for the motor.

Working Principle

The Q8010LH5, like other thyristors, works by being triggered into a conducting state. This can be done by applying a signal to the gate electrode, which then produces a current flow between the two main electrodes. This current flow can be modified by the voltage applied to the gate, allowing the user to control the level of current flowing through the device. In this way, it is able to act as a switch, turning the circuit on and off, as well as providing phase control.

When the Q8010LH5 is switched on, the voltage applied to the gate will cause the current to flow through the device in one direction, making it easier to control the current at a lower voltage. Once the circuit has been switched off, the device remains in its off state, until it is triggered again by the application of a signal to the gate.

The Q8010LH5 is an important component for controlling and regulating current in AC circuits, and is used in a wide range of applications. Its ability to quickly switch on and off, as well as its reliable performance, make it well suited for a variety of industrial and consumer applications. It is well suited for use in any circuit that requires precise control of AC current.
