Thyristors - TRIACs

Thyristors are thyristor-based power electronic switches used to control electric power functions such as motor speed control, lighting control, voltage regulation and many others. Thyristors are available in a variety of. Thyristors are divided into four categories: TRIACs, SCR, DIACs and MOSFETs. In this article we focus on TRIACs.

CTB06-1200BW Application Field and Working Principle

The CTB06-1200BW is a TRIAC-based thyristor, commonly used in motor speed control and lighting automation applications. It is a 3-terminal device with breakdown voltage of 1200V and forward blocking voltage of 6V. The CTB06-1200BW can operate in zero-cross and phase-angle modes and is available in various packages.

The CTB06-1200BW is a bidirectional switch, meaning it can either be turned off or on from either terminal (anode or cathode). When turned on, the device switches the voltage between its two terminals, allowing current to flow. The device is triggered when the current between the terminals reaches a certain threshold. The CTB06-1200BW has a maximum off-state leakage current of 40 mA and a maximum on-state current of 12 A.

In order to operate in zero-cross mode, the CTB06-1200BW requires an external alternating voltage signal. When the signal crosses zero, the device triggers and switches the voltage between its two terminals, allowing current to flow. In phase angle mode, the device has to be triggered at a certain angle in the AC waveform, typically 30-70 degrees. When triggered, the device switches the voltage between its two terminals, allowing current to flow.

The CTB06-1200BW is widely used in motor speed control, lighting control and voltage regulation applications. In motor speed control applications, the device controls the power supply to the motor, allowing the motor speed to be regulated. In lighting control applications, they can be used to switch on/off and dim lights. In voltage regulation applications, they can be used to regulate the voltage applied to the load.

The CTB06-1200BW thyristor is a popular device for controlling electric power functions such as motor speed control, lighting control, voltage regulation and many others. The device is triggered when the current between its two terminals (anode and cathode) reaches a certain threshold, allowing current to flow. The device can be operated in either zero-cross or phase-angle modes, making it suitable for a wide range of applications.
