Thyristors - TRIACs

A TRIAC is an acronym for a triple bi-directional non isolated thyristor gate turn-off thyristor and is a solid state switch with multiple-terminal connections which is used to control AC power flow in a variety of applications. The TRIAC operates under all AC voltage phases with a single switch. This makes the device particularly useful in AC motor control.

The MAC16HCMG is a 600V 16A TRIAC with a gate-trigger voltage of 12V and a on/off switching time of 15us. It is available in various packages and typical applications include lighting, heating, home automation, and solar power applications.

To understand how the MAC16HCMG TRIAC works, the basic principles of how a thyristor works need to be understood. A thyristor is an electronic device consisting of a reverse-biased p-n junction in which the gate or trigger voltage controls current conduction from anode to cathode. When the gate voltage exceeds a specific level, the thyristor can be turned on and begins to conduct current.

The TRIAC works on the same basic principle as thyristors but can conduct current in both directions. This is the property which makes TRIsACs useful AC power control devices. The MAC16HCMG has two main modes of operation: Phase Control Mode and Pulse Trigger Mode (PTM). In Phase Control Mode, the TRIAC can be used to control AC power in both directions by controlling the amount of time between the peak of the AC sine wave and the point of conduction.

In Pulse Trigger Mode, the TRIAC can be used to produce a narrow pulse of AC current. By controlling the number of times the TRIAC is triggered, the width and duration of the pulse can be changed. This mode of operation makes it possible for the MAC16HCMG to be used for applications such as inductive heating, ignition systems and fuel injection on a car.

The MAC16HCMG is a very versatile electronic component and its versatility makes it a popular choice for a wide range of applications. It is a cost-effective solution for controlling AC power in both directions and can be used to provide a controlled pulse of AC current in Pulse Trigger Mode. The MAC16HCMG is a reliable and easy to use component which is suitable for a variety of applications.
