Thyristors - TRIACs

A TRIAC (also known as TSC, triode for alternating current) is a silicon controlled rectifier designed to allow bidirectional current flow. It is used to control the flow of current in a circuit as it can be switched on and off by varying the voltage applied to it.

The MAC15SMG is an example of a TRIAC (three terminal, silicon controlled rectifier). This device is an extremely small, chip-sized surface mount device with a maximum current handling of 1.5A and an on-state voltage drop of 1.2V at room temperature. The MAC15SMG also has an operating temperature range from -45°C to +125°C. The MAC15SMG can be used in a variety of applications, including AC motor control, brushes, heating controls, switching and dimming control for LED lighting, and as alternators.

The working principle of the MAC15SMG is quite simple. When the Gate terminal is triggered and appropriate bias is applied to the Main and Auxiliary terminals, a conducting channel between the Main and Auxiliary terminals is created, allowing current to flow and the device to turn on. If the bias is removed, the conducting channel is deactivated, and the device will be in the off-state.

The MAC15SMG can be used as an on-off switch in many control systems, allowing current to flow when a trigger signal is applied and to be cut off when the trigger signal is removed. This makes it ideal for use in applications such as motor control, lighting, and heating controls, where electricity needs to be operated accurately on-demand.

In addition, the MAC15SMG can also be used as a dimming switch to vary the amount of current flowing in a circuit. This makes it ideal for applications such as LED lighting, where electricity needs to be accurately adjusted to control brightness.

Overall, the MAC15SMG is a very versatile device that can be used in a variety of applications. It is an extremely small, chip-sized surface-mount device that can accurately control the flow of current in a circuit, making it ideal for applications where electricity needs to be accurately operated on-demand.
