Introduction to TRIACs

Triacs are a three-terminal semiconductor device which is a variation of a thyristor and belongs to the electronic switch family. Triacs are commonly used for switching, phase control and dimming of high-voltage AC power. Triacs are especially useful for applications where AC sources must be activated in the same fashion.

The Structure of TRIACs

The TRIAC consists of two opposing PN junctions with two main semiconductor regions each. The two main regions of the TRIAC are called main terminal 1 (MT1) and main terminal 2 (MT2). The main terminals are located at opposite ends of the device and can be distinguished by their colour codes. The third terminal is the gate terminal, which controls the electrical flow through the device. It is the only terminal that can be used to turn the device on or off.

Operation of TRIACs

Unlike normal thyristors which only conduct in one direction, TRIACs can conduct in both directions, making them ideal for AC applications. When the gate of a TRIAC receives a positive voltage pulse, it will turn “on” and allow current to flow through the device. The gate must then be held at a positive voltage for current to keep flowing. This voltage is called the “holding voltage” and is usually around 1V.If the gate voltage is reduced or removed, the TRIAC will turn off, interrupting current flow. When this happens, the TRIAC is said to be in the “off state”. The gate voltage can then be used to turn the TRIAC back on again. The gate voltage must be maintained above the “holding voltage” in order for the TRIAC to remain “on”.

Applications of TRIACs

The most common application of TRIACs is for power control. They are widely used in light dimmers, motor speed controls, and electric stove top lighters. TRIACs can also be used in applications such as:1. Power switching2. Power regulation3. AC current sensing4. Lamp flasher circuits

CTB16-1200CPT Application Field and Working Principle

The CTB16-1200CPT is a TRIAC designed for use in power control applications. It has a maximum blocking voltage of 1200V and a maximum peak on-state current of 16A. This TRIAC can be used for switching, phase control and dimming of high-voltage AC power.To turn the TRIAC on, the gate terminal must be supplied with a positive voltage pulse greater than the holding voltage of the device. When this voltage is applied to the gate, electrons are able to move from the N-type region to the P-type region and create a conductive channel between MT1 and MT2. This channel then allows current to flow through the TRIAC.The CTB16-1200CPT is capable of operating in the partially-on or ‘controlled rectification’ mode. This mode allows the TRIAC to deliver precise control of the load current by controlling the anode-cathode conduction angle. This is done by controlling the trigger pulse width and intensity, which is altered by the anode and cathode voltage.

Conclusion

In conclusion, TRIACs are a versatile semiconductor device used for a variety of applications including power switching, phase control, dimming and current sensing. The CTB16-1200CPT is a TRIAC designed for these applications and is capable of controlling the load current by controlling the anode-cathode conduction angle.
