Thyristors - TRIACs are solid state devices that contain two junctions and two terminals. The 2N6348AG is a type of TRIAC, which stands for Triode for Alternating Current, and is used for bidirectional conduction and controlling current in AC circuits. This device has a variety of applications and is suitable for energy efficient applications because of its characteristic as a low-power device.

The device is made up of a pair of three-layer NPNP transistors in a parallel configuration, which are connected together by another transistor. This configuration acts similar to an SCR in that voltage tied between the two terminals is the trigger to turn on the device, allowing the current to flow in both directions. This is different from an SCR, because the gate voltage of an SCR is always unidirectional while the gate voltage of a TRIAC is able to control the current in both directions.

The 2N6348AG has a current rating of 0.4A for one direction and 0.3A for the other, with a trigger voltage of 3V typically. It is most often used for light-dimming applications, motor speed control and AC power switching. It can also be used for temperature controls, general rectification and triggering of thyristors. The power dissipation for the device is also very low (less than 0.2watts) meaning it is a very efficient device when used in energy sensitive applications.

The working principle of the 2N6348AG is fairly straightforward. Depending on the direction of current, the device will gate on or off. When the voltage rises over the trigger voltage, the device will switch on and current can flow in the specified direction. When the voltage decreases, the device will turn off and no current can flow through it. This makes it ideal for applications requiring a low trigger voltage and bidirectional conduction.

In conclusion, the 2N6348AG is a low-power, high efficiency TRIAC device with a variety of applications. It can be used for light-dimming, motor control, AC power switching and temperature control. Its working principle is very simple and straightforward, making it the ideal choice for energy efficient applications.
