Thyristors are a type of semiconductor which is used to control current flow in an electrical circuit. They work by commutating or converting the direction of current flow in a circuit. Thyristors are divided into two categories: TRIACs and SCRs (silicon-controlled rectifiers).

TRIACs are a type of thyristor which works by switching current flow in three directions, making them suitable for AC circuits. A single TRIAC device can replace two SCRs for AC circuit control. A TRIAC has three terminals called an ‘Anode Gate’, a ‘Cathode Gate’, and a ‘Main Terminal’. Current can flow between the ‘Main Terminal’ and either of the two ‘Gate Terminals’ when the TRIAC is ‘turned on’, letting current flow from one terminal to either of the others.

The MAC97A8/DG,116 is a type of silicon-controlled TRIAC. It is a four layer device, specifically designed for alternating current (AC) line applications. It has three contacts: gate, main, and main2. The main2 contact, which is also connected to the main terminal, is typically guarded in an AC application circuit with a capacitive connection. The gate terminal is used to determine the device’s firing angle, which affects the amount of control of the current supplied to the device.

The MAC97A8/DG,116 offers excellent performance in the following applications: AC line currents up to 6A, forward surge currents of up to 30A, and break-over current of up to 60A. Due to its ability to handle higher current levels, this device can be used in a variety of applications such as light dimmers, intelligent relays/switches, power supplies, and motor controls.

The maximum breakdown voltage of the MAC97A8/DG,116 stands at 600V, and its typical turn-on time stands at 40µs. The device is also able to operate at temperatures ranging from -40°C and 125°C. However, the device has a maximum storage and operating temperature of 150°C and 110°C respectively.

The working principle behind the MAC97A8/DG,116 is based on a bipolar junction transistor (BJT) and two SCRs. When a current passes through the mac97A8/DG,116, the main terminal is activated and the SCRs are triggered. This activates the BJT, which allows current to flow between the main and the gate terminal. When the current at the gate reaches the breakdown voltage of the SCR, the TRIAC is triggered and the device begins conducting.

In summary, The MAC97A8/DG,116 is a type of four layer silicon-controlled TRIAC that is specifically designed for use in AC circuits. It has three contacts and can handle up to a 6A current. It is suitable for a range of applications, such as light dimmers, power supplies and motor controls. The working principle behind the device involves a bipolar junction transistor and two SCRs.
