Introduction to Thyristors - TRIACs

Thyristors - TRIACs are a type of three-terminal semiconductor device. They are used in a wide range of applications, from logic controllers and industrial automation systems to telecommunications and consumer electronics. The main advantage of using TRIACs is their ability to rapidly switch a high voltage, allowing them to be used in a variety of applications. TRIACs are mainly used to control the amount of current being passed through a circuit, and can be used to control AC or DC power.

QJ4016LH4TP Application Field and Working Principle

The QJ4016LH4TP is a zero-crossing type TRIAC designed for AC power control applications. It is a standard sensitive and gate type device, meaning it is triggered by a low power input to the gate terminal. This allows the TRIAC to be triggered at a precisely determined point within a half AC cycle, making it useful for applications where precise power control is required.The QJ4016LH4TP is designed for high-power switching and has a maximum drain current rating of 16A. The maximum voltage rating for the QJ4016LH4TP is 400V. The QJ4016LH4TP also has a snubberless design, meaning it is capable of switching at high frequencies without the need for an external snubber network.The working principle of the QJ40106LH4TP is quite simple. When a voltage is applied to the gate terminal, it causes the TRIAC to start conducting current in both directions. The device will continue to conduct current until it reaches the rated voltage rating. Once the voltage reaches this threshold, the TRIAC will stop conducting current until the gate voltage is removed. This makes the device suitable for use in applications where precise control of power is necessary, as the device can be tuned to turn on at a precisely determined voltage.

Conclusion

The QJ4016LH4TP is a reliable and cost-effective zero-crossing type TRIAC designed for AC power control applications. It is capable of switching high voltages quickly and accurately, making it suitable for a variety of applications. The device also features a snubberless design, allowing it to switch at high frequencies without the need for an external snubber network. The QJ4016LH4TP is an ideal solution for applications that require precise control of AC power.
