Thyristors - TRIACs

TRIACs are a type of thyristor, a type of power semiconductor device that allows the current to flow in either direction. They can be used to adjust or switch the amount of current flowing in a circuit. TRIACs are widely used in applications such as motor drives, lighting control, temperature control, and speed control. They are also found in consumer electronics, such as TV sets, computer monitors, and microwave ovens.

Z0109MN,135 application field and working principle

The Z0109MN,135 is a standard medium-power TRIAC that is used in a number of industrial, as well as consumer electronics, applications. It is an integrated device that contains two independent thyristors, one connected to each of the three terminals on the package. This allows the TRIAC to be used in circuits that require the control of both positive and negative current flow.

The working principle of the Z0109MN,135 can be attributed to its two thyristors. A thyristor is a type of power semiconductor device that consists of four layers of semiconductor material, divided into three regions. The three regions, namely the anode, the gate and the cathode, are connected to the circuit externally and are used to control the flow of current in the circuit. The gate acts as the controlling switch and is used to turn the thyristor on and off. When the gate is triggered, the two thyristors will conduct current in both directions, which allows the current in the circuit to be adjusted or switched.

The Z0109MN,135 is designed to operate across a wide voltage range of 250V to 600V, and allows currents up to 9A. It is designed to operate under a variety of temperature and humidity conditions. Its maximum junction temperature is 150˚C, and the maximum allowable case temperature is 85˚C. It is suitable for applications where AC input is required, such as motor and lighting control, as well as temperature and speed control.

In conclusion, the Z0109MN,135 is a medium-power TRIAC that is suitable for a variety of AC input applications. It can be used to adjust or switch the amount of current flowing in a circuit, and is designed to operate across a wide voltage range and temperature range.
