MAC16HCM

Thyristors - TRIACs is a type of semiconductor which is a three- terminal device with two diodes connected in series and two resistors connected in parallel. TRIACs are characterized by their ability to switch current in both directions and their ability to be triggered and turned on or off with a single pulse. The main application of TRIACs is AC power control and bidirectional switching.

The MAC16HCM is a type of TRIAC designed for the power control market. It is an isolation-type TRIAC with an integrated heat sink for improved heat dissipation. As with other TRIACs, the MAC16HCM has three terminals: the gate, the main, and the anode. It can control a load current from 0.5A to 16A in single-phase applications and up to 10A in three-phase applications. The MAC16HCM has an isolation barrier between the gate and main terminals which prevents the gate current from damaging the control circuitry. It also has a surge rating of 40A, which makes it suitable for use in applications with high inrush currents.

The working principle of the MAC16HCM can be summarized as follows. It functions as an AC switch and controls the power supply of loads installed on the main\anode terminal by controlling the conduction angle. When a positive voltage is applied to the gate terminal, the main and anode terminals become conductive and the load current flows. When the gate voltage is zero or negative, the main and anode terminals become nonconductive and the load current is cut off. The conduction angle of the MAC16HCM is controlled by the gate control voltage and its on-state current is limited by a power resistor.

Due to its isolation barrier and high surge rating, the MAC16HCM is ideal for AC power control applications such as motor speed control, air conditioning control, and home appliance control. It is also suitable for DC control applications such as lighting control, motion control, and dimming control. The MAC16HCM is also used in applications where protection from high transient over-voltages is required, such as variable frequency drives.

In conclusion, the MAC16HCM is a highly versatile TRIAC designed for power control applications. With its isolation barrier and high surge rating, it is suitable for use in a variety of AC and DC control applications. It is also used in applications where protection from transient over-voltages is required.
