Thyristors - TRIACs are a type of semiconductor device found commonly in electronic devices. The BT137-600/DG,127 is one such instance of a TRIAC being used within a variety of applications. This article will look into the application fields, as well as how the device works.

Applications

The BT137-600/DG,127 is a type of gate-triggered triac typically used in control, protection and isolation circuits. Specifically, it is usually used for medium power AC switching, driving relays or other loads and for controlling light dimming applications such as in tungsten halogen lamps and incandescent lamps.

In terms of medical applications, the BT137-600/DG,127 is commonly used on X-ray machines, MRI systems, and motherboards for various medical devices. It is also seen in household appliances such as fans, dishwashers, washing machines and dryers. More recently, the BT137-600/DG,127 has been used in LED dimming applications as well.

Working Principle

The BT137-600/DG,127 is a three-terminal thyristor which, when triggered by an external signal, controls the flow of electrical current in a predetermined manner. The device consists of two PN-junctions connected in reverse parallel, and are triggered in the same direction. As a result, the BT137-600/DG,127 is able to carry current in both the forward and reverse directions.

When a voltage or current is applied to the gate, the device is turned on, and when the voltage or current is removed from the gate, the device is turned off. This can be used to control the flow of both AC and DC currents, making it an excellent choice for use in light dimming applications. Additionally, the BT137-600/DG,127 is able to stand off high voltages, making it suitable for use in high voltage circuits.

Conclusion

The BT137-600/DG,127 is a gate-triggered triac that is commonly used in a variety of applications, including X-ray machines, MRI systems, and motherboards for various medical devices. It is also seen in household appliances such as fans, dishwashers, washing machines and dryers. Lastly, more recently it has been used in LED dimming applications as well. The device is triggered by an external signal and is capable of controlling the flow of both AC and DC currents, making it an effective choice for light dimming applications.
