Thyristors - TRIACs are an important family of semiconductor devices which act as an electrical switch to control electrical energy but with features that make it ideal for AC power circuits. The MAC15MG is one type of Thyristor - TRIAC that can be used in various consumer, industrial, and automotive applications. This article will discuss the application field and working principles of MAC15MG.

Applications

Doubler circuits, motor control, AC control and light control are some of the most common applications for MAC15MG TRIACs. The device is designed with a high surge current rating and a low trigger voltage making it very reliable in these applications. It can also be used in heating, lighting, and reed relay applications.

The device is suitable for a variety of AC switching applications including low cost lamp dimmers, electronic door locks, fan control circuits, solid state relays and other AC current control circuits. It is used to control power to DC motor loads, fluorescent light dimmers, fluorescent ballasts, and AC motors. It is also used in the control of power switching of inductive loads.

Working Principle

The MAC15MG is a sensitive gate, three-quadrant TRIAC with a maximum blocking voltage of 500V. It contains three terminals: Anode 1, Anode 2, and Gate. When a voltage is applied across the Anode 1 and Anode 2 terminals and a current is applied to the Gate terminal, the device will become ON, allowing current to pass through it. When the Gate current is removed, the device will become OFF, blocking current flow.

The Gate terminal is configured to turn the device ON when the voltage reaches a certain threshold (on-state voltage) and also turn it OFF when the voltage reaches a certain threshold (off-state voltage). The correct Gate current applied through the Gate terminal will keep the MAC15MG in a conducting state, allowing continuous passage of current through the device. This makes it ideal for controlling the AC current in circuits.

The MAC15MG is also designed with a design feature known as “snubberless”. This feature eliminates the need for an external resistor-capacitor circuit, or “snubber”, for reverse voltage protection. This makes the device both cost effective and easy to use.

Conclusion

The MAC15MG is a high voltage, three-quadrant TRIAC with a sensitive gate that is ideal for AC switching applications. It has a high surge current rating and a low trigger voltage making it reliable and cost-effective. In addition, it has a “snubberless” design feature that eliminates the need for an external resistor-capacitor circuit, or “snubber”. Therefore, it is an excellent choice for applications such as lamp dimmers, fan controllers, door locks and AC current control circuits.
