Thyristors or Silicon Controlled Rectifiers (SCRs) are a family of semiconductor components that are used, on an industrial scale, for voltage and current regulation. They are commonly used in electric power converters, power controllers, and power supplies. They are also used in many other industrial loads and devices.

Thyristors are also used as switches that are operated through the application of a suitable triggering signal. In this application, thyristors are referred to as a thyristor switch. The family of thyristor switching devices includes TRIACs, Silicon Controlled Switches (SCSs), and Thyrister switches.

The MAC228A4G thyristor is a TRAC, or Thyristor Reactive AC switch, used for power control and regulation applications. It is composed of a junction core with three terminals, each with its own specific function. The MAC228A4G is suitable for applications with power up to 2KW and for voltage control up to 48 Volt (V). It has high efficiency, long life, and is high current and reliable.

The primary application area for the MAC228A4G is the control of voltage of electrical motors, heating elements, and lighting systems. It can also be used in solid state relays in household appliances, transformers and other systems that need high accuracy and reliability. Additionally, the MAC228A4G can be used as a starter for electric pumps, wheels and other motor-driven applications.

The working principle of the MAC228A4G is simple. When it is turned ON, a low voltage is applied to its Gate terminal, and a large current flows between its main terminals (MT1, MT2). The Gate terminal is designed to ensure a smooth switching of the current flow. When the Gate terminal is grounded, the current flow is inhibited, thus providing current control. The Gate threshold voltage is adjustable, which allows precise control of the current.

In addition to its primary function of controlling the voltage and current, the MAC228A4G also provides protection against thermal and electrical overloads. It also has low on-resistance of 2 milliohms, which eliminates unnecessary power losses. This feature makes it an excellent choice for power control applications.

The MAC228A4G is a high-performance thyristor switch capable of delivering reliable and reliable power control and regulation. Its smooth switching, adjustable Gate threshold voltage, low on-resistance, and thermal and electrical overload protection make it an ideal choice for industrial voltage and current regulation applications.
