Thyristors - TRIACs: MAC12SNG Application Field and Working Principle

The MAC12SNG is a thyristor, which is specifically a 3-quadrant gate-controlled thyristor, and more commonly known as a Triode AC Switch (TRIAC). This is a type of design which allows AC currents to be switched on and off, but can also be used as a bidirectional device, operating over one or more AC cycles.

This device has a very wide acceptance range in terms of main parameters, with a peak current of up to 12A, a hold current of 12A, an on-state voltage of 55V-400V, an on-state resistance of less than 0.2ohm, and an off-state volt of less than 6V. It can be widely used for universal AC switches, micro-driven high frequency switching, DC fan motor speed control, and overvoltage surge protection.

The working principle of the MAC12SNG is quite straightforward. It is essentially like a switch that turns on the current flow only when a certain voltage is applied across it. By varying the voltage, it is possible to regulate the amount of power that it will output. When the switch is first turned on, it will start to apply a certain amount of current to the circuit. This current will increase until the voltage reaches a certain level which is determined by the forward bias voltage of the Gate. At this point, the Triac will turn off and the current will drop to zero.

The TRIAC also has a reverse bias voltage which is determined by the amount of current drawn by the load in the circuit. When the current drops below a certain point, the TRIAC will start to conduct current in the reverse direction and apply it to the circuit. This process repeats itself until the switch is turned off.

The MAC12SNG from Thyristors has many advantages compared to other thyristors, such as its reduced dissipation (less than 0.2 ohm) and increased temperature stability, and its ability to function at high frequencies, making it suitable for a wide range of applications. It is also versatile in terms of its gate control, allowing for more precise control of the power output.

Overall, the MAC12SNG is a reliable, high performance thyristor with a wide range of application possibilities, making it suitable for many different types of applications. It is able to function over a wide range of temperatures and voltages, and offers an efficient, stable, and cost-effective solution for switching AC currents.
