Thyristors are electronic components that act as switches and provide an inherent control to the current they supply. In particular, TRIACs, or TRIodes for Alternating Current, are three-terminal thyristors that can control current in both directions. One of the most versatile and popular types of TRIACs used today is the QJ6016RH2TP. This article looks at its application field and working principle.

Application Field

QJ6016RH2TP is a general-purpose TRIAC with a domain ranging from -50A to +50A. This makes it suitable for a wide range of tasks and applications, such as light dimmers, motors, lamps, and home appliance control. Furthermore, its high surge current handling capabilities make this TRIAC a good choice for applications that require a better start-up, like DC motors. In addition, its high differential temperature coefficient gives it good sensitivity and thermostability over a wide temperature range.

In addition to its residential applications, the QJ6016RH2TP also has wider industrial uses. Because its off-state blocking voltage is high and its on-state current rate is low, this TRIAC can protect circuits that are oftentimes prone to overvoltage and thermal overload. Furthermore, its high insulation resistance ensures high reliability and consistent performance in industrial applications.

Working Principle

The working principle of the QJ6016RH2TP is based on the switching of a single thyristor. It works by using two diodes connected in opposite directions, thus allowing current to flow in both directions from the anode to the cathode. When the current reaches the threshold voltage (VGT), the thyristor is triggered and the current is allowed to pass. When the current passes through, the thyristor enters the on-state and stays in it until the current is stopped. It should be noted that the current can only pass through in one direction and needs to be switched in order to be used for a different purpose.

The QJ6016RH2TP also features protection features like the temperature protection and overvoltage protection, which helps to protect circuits from unintended damage. For example, when the temperature of the TRIAC exceeds the maximum threshold, its temperature protection feature will shut off the flow of current and prevent any further damage to the circuit.

Conclusion

The QJ6016RH2TP is a very versatile TRIAC capable of a wide range of residential and industrial applications, thanks to its dual-direction current flow, temperature protection and overvoltage protection. Its use in a wide range of scenarios makes it a reliable and trustworthy option for many applications.
