Introduction to Thyristors - TRIACs

Thyristors are solid-state electronics components that are used in many electrical and electronics systems. They are a key device used in many power-control applications, such as motor and lighting controls, inverters, and DC power supplies. They also find use in computers, telecommunications systems, and other control system applications. TRIACs are a type of Thyristor that are specifically designed for use in on-off control applications.

QK016NH6TP Overview

QK016NH6TP is a TRIAC used for interrupting currents of up to 16A AC in mains frequency voltage circuits. It has sensitive gate characteristics, which mean it triggers for low gate currents. It can be used for alternating and direct current control, with resistive and inductive circuits. It features a two-quadrant mode. This means it can conduct in both directions on activated gate current, making it useful for phase angle conduction.

QK016NH6TP Application Field

QK016NH6TP is suitable as a switching device in a variety of fields and industries. Its practical application includes AC motor control, home heating and lighting control, DC power supplies and other power control applications. It is also used in electric trucks and automotive systems, industrial lighting control, induction motor control and material handling systems.

QK016NH6TP Working Principle

The working principle of a TRIAC is similar to that of a thyratron. It consists of three semiconductors connected in series: an anode, a gate, and a cathode. When a suitable electric current passes through the anode and the gate, they create an electric field which causes electrons to be emitted from the cathode. This causes a current conduction in the circuit, and the TRIAC then begins to conduct.When the gate current is turned off, the TRIAC will turn off as the electric field is no longer present. The TRIAC will turn off even if the main current is still flowing in the circuit. The TRIAC can also be turned off by reversing the main current in the circuit, which causes the electric field to be reversed and the TRIAC to turn off. This is known as the \'commutation\' process.

Conclusion

QK016NH6TP is a TRIAC that is suitable for use in many fields and industries. It has a sensitive gate and can be used in alternating and direct current applications. Its working principle is similar to that of a thyratron, with a three-semiconductor series made up of an anode, a gate, and a cathode. This provides on-off control with resistive and inductive circuits. It is especially useful for phase angle conduction due to its two-quadrant mode.
