Thyristors - TRIACs: QJ6016LH2TP Application Field and Working Principle

Thyristors are an important class of semiconductor devices that act like switches, controlling the flow of electricity going through the circuit. TRIACs (Triode for Alternating Current) are a special type of thyristor that can control both positive and negative parts of the AC signal. The QJ6016LH2TP is a 600V/16A off-line medium power TRIAC that is designed for use in a wide range of industrial and home applications. This article will explain the application fields for the QJ6016LH2TP and its working principle.

Application Fields for the QJ6016LH2TP

The QJ6016LH2TP is an ideal medium power TRIAC for applications such as light dimmers and motor speed controllers in air conditioners, refrigerators, and washing machines. The QJ6016LH2TP can also be used for industrial and commercial applications such as electronic door locks, access control systems, motor speed and direction control devices, and various other motor control applications. This TRIAC has a thermal limit structure that can prevent overcurrents, overvoltages, and high temperatures. As such, it is suitable for a variety of high-power applications, such as welding machines, power supplies, lighting switching, and electric heaters.

Working Principle of the QJ6016LH2TP

A TRIAC is an electronic component that consists of three chambers: the gate, main and alternate. The TRIAC is connected to a power source and a load, and it has a terminal, called the gate, which is triggered when a positive or negative voltage is applied to it. This triggers two turn-on functions that allows the TRIAC to conduct in both directions. The main chamber switches the flow of current between the power source and the load in the positive direction while the alternate chamber is used to switch the current in the negative direction. The gate initiates current flow in the main chamber, and then the alternator takes over the control of current flow in the opposite direction.

The QJ6016LH2TP is designed to offer a wide range of features, including zero cross-over (no sawtooth waveform), fast switching, and AC line protection. It also has a high surge current capability, over-current protection, and temperature sensing. These features make it suitable for a variety of high power applications.

Conclusion

The QJ6016LH2TP is a medium-power TRIAC designed for use in a wide range of applications, from consumer electronics to industrial motor control. Its unique thermal limit structure provides high-temperature protection and over-current protection. The TRIAC works by triggering two turn-on functions that allow it to conduct in both directions. The QJ6016LH2TP is a reliable and efficient medium power TRIAC suitable for a variety of applications.
