Thyristors are widely used in power control and switching applications as reliable, efficient devices with several advantages. The use of TRIACs (Triode for Alternating Current) is especially attractive when controlling the current flow in AC circuits, as it allows for both positive and negative supply current control. The Q4016RH4 is an advanced 600V triac that is specifically designed for use in AC switching applications. In this article, we will look at the Q4016RH4\'s application fields and working principle.

Application Fields of the Q4016RH4

The Q4016RH4 is suitable for many different AC switching applications. In particular, it is often used in universal motor control, including control of air conditioners, pumps and fans. It is also suitable for use in versatility control systems like light dimmers, solenoid valves, as well as various other power control applications. In addition, it can also be used for single-phase AC switching for appliances such as electric cooking appliances and hairdryers.

Working Principle of the Q4016RH4

The Q4016RH4 is a three-terminal device with the gate and main terminals connected to the AC supply voltage, while the third terminal allows for the control of the device. The device operates in two stages, a cut-off stage and a conducting stage. In the cut-off stage, the gate is held at a potential lower than the potential of either of the main terminal, thus inhibiting the flow of current to the device. On the other hand, in the conducting stage, the gate is held at a potential higher than the potential of either of the main terminals, thus allowing current to flow through the device. This two-stage process means the current flow can be easily controlled.

The Q4016RH4 also features a high surge capability, allowing it to be used in applications with high inrush currents. In addition, it has a high current carrying capacity for its size and is capable of withstanding high temperatures. Lastly, it has a high turn-off current capability, ensuring that it can quickly break the current at even higher currents.

Conclusion

The Q4016RH4 is a reliable, efficient device that can be used in many AC switching applications. It is suitable for applications with high inrush currents, and its high current carrying capacity makes it a great choice for applications that require quick, accurate control of the current flow. Its high turn-off current capability is also a major benefit, ensuring that current is quickly broken even when handling larger currents.
