MAC15A10G

Thyristors - TRIACs

The MAC15A10G is a 15A medium current TRIAC (triode for alternating current) widely used in industrial, residential, and commercial applications. TRIACs are widely used to control electrical power because they do not require a current or voltage source to control the conduction angle of the current or voltage waveform.

The MAC15A10G has three terminals - Gate, Main, and Anode - and is connected in series with the load. It acts as a switch, turning on and off the current flowing in the main terminals as a result of application of a voltage to its gate terminal. Due to its symmetric operation, the MAC15A10G is suitable for AC loads in applications where light dimming and speed control are needed. Examples are residential lighting, appliance regulation, lighting control, and motor speed control.

The working principle of the MAC15A10G is simple. When the Gate terminal is triggered with an appropriate level of voltage or current, a conducting channel is formed between the Main and Anode terminals that allow current to flow freely. This is known as the “turn-on” state. When the Gate voltage or current is reduced or missing, the conducting channel is broken, and the Main and Anode terminals are no longer connected. This is known as the “turn-off” state. In its turn-off state, the MAC15A10G is completely non-conducting, which means that any current drawn through the main terminals will be blocked.

The MAC15A10G’s ability to control conduction angle makes it suitable for applications that require precise control. For example, it can be used to adjust the speed of a motor by correlating the Gate voltage or current with the speed of the motor, allowing for faster or slower operation. It can also be used to control the brightness of lighting in a room by varying the conduction angle applied to the lighting. Additionally, the MAC15A10G can be used in applications where repetitive pulse triggering is required for the control of inductive loads.

In conclusion, the MAC15A10G is a versatile and reliable TRIAC that offers excellent performance and control over AC loads. Its gate terminal can be used to control the conduction angle of the current or voltage waveform, making it suitable for applications that require adjustable performance. The three terminals – Gate, Main, and Anode – allow it to be easily integrated in circuit designs, or energized with an external source, such as a light dimmer, for precise control. Its unique symmetric operation and efficient triggered turn-on and turn-off make it a popular choice for many industrial and commercial applications.
