Thyristors - TRIACs : QJ4016RH2TP Application Field and Working Principle

A TRIAC, or TRIode for Alternating Current, is a three terminal, bidirectional semiconductor device used for controlling electrical power. It is a type of thyristor and is similar in function to a diac. The QJ4016RH2TP is a 16 amp, 600V TRIAC.

This TRIAC has a variety of application fields, ranging from motor control applications to general AC switching. It is very popular in power supplies and lighting, and can be used in various permutations to achieve both AC and DC switching. It is also used in dimmer circuits, where varying amounts of energy are fed to lights in order to adjust the brightness and in surge protection systems, where signals are regulated to protect circuits from damage.

The QJ4016RH2TP is constructed using a layer of metal between two rectifying layers, and it can be triggered when a suitable gate current is applied to its gate electrode. When triggered, the device turns on, allowing current to flow through it, and remains on until the load current drops below a certain threshold. When this occurs, the device automatically turns off. This operation ensures silent operation, no sparking, and low losses in the device.

The QJ4016RH2TP is compatible with a range of gate triggers, and as such can be used in many different AC switching applications. For example, it can be used with an SCR trigger, a TRIAC driver, or even a PWM control. This makes it a versatile device for any control task that requires AC mains switching.

The QJ4016RH2TP can also be used in DC switching applications, where it can be used to control the power flow in DC circuits. The device ensures that current flows only when a suitable gating source is applied to the gate terminal. The benefit of using the QJ4016RH2TP in such applications is that it eliminates the need for complex circuitry, thus saving time and cost associated with the project.

To conclude, the QJ4016RH2TP is a versatile TRIAC which is suitable for a range of AC and DC applications. It is easy to use and cost-effective, and can be used in many applications such as motor control, lighting, surge protection, and DC switching.
