Thyristors - TRIACs

MAC4DLM-001 is a type of TRIACs, which are a specific type of thyristors, otherwise known as bidirectional triode thyristors or thyristor application field and working principle. The main application of MAC4DLM-001 is in dimmer switch, lighting and power circuits. AC power control is its main characteristics which is a three terminal passive semiconductor device with one anode, one cathode and a gate terminal.

Application

The MAC4DLM-001 can be used in applications such as AC dimmer switch, lighting dimmer, AC motor control, and AC power control. It can be used to control the output power, intensity, and other parameters like speed, in a device range from 10 to 200V AC, meaning it is possible to use the device for low voltage applications up to high voltage ones. The device can handle up to 18A and 650V of current and voltage.

Working Principle

The working principle of the MAC4DLM-001 is based on the bidirectional blocking conduction of the device. As its anode voltage is changed by a control current, the device starts conducting in both directions. The amount of conduction is controlled by the control current, the voltage levels and the phase of the applied voltage. By controlling the phase of the voltage, this TRIAC can be used to detect the time point of phase commutation on AC side.

Main Features

The main features of the MAC4DLM-001 are high commutation speed, low drive voltage, high avalanche rating and typical zero current switching capability. It also has a high di/dt capability and low turn-on power dissipation. In addition, the device is built with short circuit protection and has high thermal stability.

Conclusion

The MAC4DLM-001 is a type of industry-standard TRIAC, which is suitable for power control of motor, heater and light applications. Its bidirectional conduction allows for a wide range of applications, from low voltage to high voltage and from dimmer switch to AC motor control. It also offers low drive voltage, high thermal stability and short circuit protection, needing only control current and voltage to activate.
