Thyristors - TRIACs

The CTA08-1200SWPT is a specialized thyristor composed of two thyristors connected back-to-back with their gates joined in common. The CTA08-1200SWPT is commonly known by its old name, TRIAC. TRIAC stands for " Triode for Alternating Current". It is widely used in light dimmers, motor control and other AC circuits for light modulation and on/off switching.

The working principle of a TRIAC is based on the concept of the alternating current (AC) switch. When an AC current passes through a TRIAC, it triggers the TRIAC to switch on, causing the current to flow freely. When the AC voltage reverses its direction, the TRIAC switches off, stopping the current from flowing. This switching action can be controlled by varying the voltage applied to the gate of the TRIAC.

The CTA08-1200SWPT is mainly used in lighting applications and offers a very broad range of features and benefits. It has a two-stage triggering system which allows for very precise current control and manual testing. It also incorporates a soft start to reduce the impact of transients on the load and has reverse polarity protection.

The CTA08-1200SWPT is a very versatile device that can be used in a range of applications. It can be used for light dimmers, motor speed control, on/off switching and lighting control. It is an ideal choice for applications where precise current control is required, such as light dimmers, particularly in home automation systems.

The CTA08-1200SWPT is an excellent solution for lighting control in residential and commercial applications. It can be used in a variety of lighting applications such as incandescent, halogen, and fluorescent bulbs. The device offers good performance and reliable operation, and is also suitable for controlling motors that drive fans, pumps, and other equipment.

The CTA08-1200SWPT can also be used for AC motor speed control. It offers users a low cost, low power consumption solution for motor speed control. The device operates in a wide range of AC voltages and can handle loads up to 6A.

In summary, the CTA08-1200SWPT is a very versatile device that can be used in a range of applications for switch-on and speed control. It is an excellent choice for commercial and residential applications, offering good performance and reliability.
