Thyristors - TRIACs are a special class of semiconductor components that work as a form of AC switches. The acronym standing for “Triode for Alternating Current”, these units are basically achieved by connecting a pair of thyristors back to back so they both trigger at the same time. TRIACs have become essential, popular components across numerous industries. ORP Thermistor Designs’ Q601E3RP component is a great example of such a component, which is suitable for a range of different applications.

Application Field of the Q601E3RP

Ideally, this component is designed for industrial use, although it is suitable for other applications as well. It is designed for use in a range of AC voltage and current applications, such as with solenoids, electric motors, heaters, power supplies, and light dimmers. In particular, the component can handle up to 40 A rms in a 600 V environment, and has a power rating of 200 W. It is also suited to temperature control, as it has a temperature range of -20°C and +110°C. In summary, these TRIACs can replace traditional mercury relay systems with an electricity-controlled system.

Working Principle of the Q601E3RP

The Q601E3RP has three different terminals, namely the main terminals 1 and 2 and the controlling terminal (G). Depending on the current flow in the main terminals, there are different modes of operation. The first mode is known as the Forward Blocking Mode (also called the Off Mode). When the current from terminal 1 to terminal 2 is lower than a certain threshold value, the TRIAC will be in an off position and no current will flow through it. The second mode is the Reverse Blocking Mode, which is also called the On Mode. Once current reaches a certain threshold value, the unit will trigger and the current flow from terminal 1 to terminal 2 will be enabled. The final mode is known as the Holding Mode, and in this mode, the TRIAC will remain on regardless of the current level from the G terminal.

Conclusion

The ORP Thermistor Designs’ Q601E3RP is a relatively new and highly reliable TRIAC suitable for a range of AC currents and voltages. The mode of operation is different depending on the current levels within the main terminals and the controlling terminal, with the most important being the On Mode, which is triggered when the current of the main terminals reaches a certain threshold. This component has a different range of applications, such as solenoids, electric motors, heaters, power supplies, and light dimmers, making it an essential and popular component across various industries.
