Thyristors - TRIACs

A TRIAC is a three-terminal power semiconductor device primarily designed for use in AC circuits as an ON/OFF switch. A TRIAC is an abbreviation for "Triode for Alternating Current" and is a form of thyristor, which is a current-control semiconductor device based on a three-layer silicon structure. The BTA208-600E is a type of TRIAC that is commonly used in AC switching applications.

127 Application Field

The BTA208-600E is used in a variety of applications due to its low cost and easy to install features. It is well-suited for load control, motor speed control and lighting control applications, as well as for applications that require AC switching with precise timing control. It can also be used to control the power supply of various devices such as home appliances, computer peripherals and industrial machinery.

Working Principle

When a voltage signal is applied across the gate and main terminals of the BTA208-600E, the device is triggered and turns on. This causes the current to flow through the device and the load is switched on. When the voltage signal is removed, the TRIAC turns off and the current flow stops. The BTA208-600E uses the principle of controlled avalanche breakdown of a PN junction to control the current flow. This means that the current flow can be accurately controlled over a wide range of current levels, making the BTA208-600E a very useful device for numerous AC switching applications.

Conclusion

In summary, the BTA208-600E is a type of TRIAC (Triode for Alternating Current) that is used in AC switching applications requiring precise timing control. It offers a low cost and easy to install solution for load control, motor speed control, and lighting control applications. The BTA208-600E is triggered when a voltage signal is applied across its gate and main terminals, and uses the principle of controlled avalanche breakdown of a PN junction to control the current flow.
