MAC12HCM

Thyristors - TRIACs

The Mac12HCM is a type of Triac (Triode for Alternating Current), which is a thyristor device akin to a diode but it is capable of working with both polarities of a signal. It is essentially two SCR’s (Silicon Controlled Rectifiers) which are connected in series but integrated into a single package. This produces a switch that can handle both positive and negative signals and thus allow for AC current.

The Mac12HCM is a very sophisticated triac device and is typically found in devices with high power requirements, such as electric motors, HVAC systems, and home appliances. It is specifically designed for high frequency operation and is capable of handling currents up to 12A and voltages up to 600V. It has a low and uniform gate sensitivity which allows for better control of the triggering of the device.

Application Field and Working Principle

The Mac12HCM is primarily used in high-power industrial and commercial applications, where its ability to control 5 to 12A of current is required. It is most commonly used in motor control circuits, speed controllers and dimmer controls. In addition, it is often used in HVAC systems, air conditioning and refrigeration systems, electric stoves and ovens, and other large home appliances.

The operation of the Mac12HCM is based on the principle of the TRIAC, which is essentially two SCRs connected in reverse parallel and triggered by a gate signal. The gate signal is used to control the current flow in both directions, thus allowing for the current to be adjusted. The TRIAC remains in the “on” state until the current drops below a certain level, or until a current reversal occurs.

The Mac12HCM is a sophisticated and powerful device and is capable of controlling up to 12A of current at 600V. It offers a low and uniform gate sensitivity which makes it easy to control the triggering of the device. The Mac12HCM is a reliable and durable device and is often used in industrial and home applications where high-power switching is needed.
