Thyristors - TRIACs

The QJ6025NH6RP is a TRIAC (TThis Iway ACtroller) thyristor, which is a semiconductor device commonly used to control the power of an AC (alternating current) circuit. TRIACs are three terminal devices and have a main control terminal – the gate – that is used to turn the device on and off. It is an electronic switch that can be triggered by either anode or cathode signals.

This type of circuit functions by utilizing the control signals present within the AC circuit. When triggered, a TRIAC will start to conduct and remain conducting until the current falls to zero. The QJ6025NH6RP can switch on and switch off an AC current with a current rating of 6A and a working voltage of 400V.

Application field

The QJ6025NH6RP is widely used in applications where AC power needs to be actively controlled, such as AC motor speed control, light control, heating/temperature control, power switching, etc. The device is also used in various industrial and consumer applications such as heating control systems, consumer appliances, AC motor speed controllers and lighting control systems.

Working principle

The operation of the QJ6025NH6RP is based on a thyristor device in which current flows between two terminals. When triggered, the device will start to conduct and remain conducting until the current falls to zero. The device can be triggered by either anode or cathode signals. A gate control current is also required to activate the device. The gate current is used to turn the device on and off and determines the operating current of the device. The device also features a thermal shutdown feature that turns off the device when the temperature of the device is too high.

The device will remain off until the voltage or current exceeds a certain limit. If the voltage and current remain over the limit for too long, the device will become overload and shut off automatically. This provides a measure of safety as it prevents the device from drawing too much current and causing damage to the circuit.

The QJ6025NH6RP is suitable for applications where it is necessary to actively control the flow of AC power such as motors, lighting controllers, and heating/temperature control systems. The device also features a thermal shutdown feature that provides a measure of safety as it prevents the device from drawing too much current and causing damage to the circuit.
