Thyristors - TRIACs are components of semiconductor devices, most commonly used in the field of power management and motor control in many electrical and electronic equipment. Among them, CTB08-1200CWPT is one of the widely used one.

Introduction
CTB08-1200CWPT is a high-performance bi-directional AC trigger switch widely used in various home appliances. It owns many advantages such as low operation power, high long-term stability, good electrical and thermal properties and so on.

Application Field
CTB08-1200CWPT can be extensively applied in a variety of electronic switches such as thermostats, fan speed controllers, washing machines, air compressors, microwave ovens, electric heaters, household electric appliances, small displacement pumps and lighting equipment. Especially, it is quite suitable for controlling a wide range of automatic commutation motors and is suitable for A.C. Control in households and electronic switches.

Working Principle
The CTB08-1200CWPT is mainly composed of three layers of high-power semiconductor materials. Attached to an AC power source is a pair of silicon metal-oxide-semiconductor (MOS) transistors connected in series. An external trigger signal is then sent to the gate terminal of the two transistors, which will then allow current to flow through them. As the current flows through the transistors, the negative voltage of the transistors will increase, which will then cause the two semiconductors to become conductive, generating a negative charged pulse. The conduction process will continue until the input current is turned off by the external trigger signal. And this is the working principle of CTB08-1200CWPT.

Conclusion
CTB08-1200CWPT is a high-performance bi-directional AC trigger switch widely used in various home appliances, for its advantages in low operation power, high long-term stability, good electrical and thermal properties. It can be applied in many electronic switches, especially for controlling a wide range of automatic commutation motors and is suitable for A.C. Control in households and electronic switches. The working principle of CTB08-1200CWPT is that external trigger signals are sent to the gate terminal of the two transistors which will then allow current to flow through them, and the conduction process will continue until the input current is turned off by the external trigger signal.
