Thyristors - TRIACsA TRIAC, or a triode for alternating current, is a three-terminal switch suitable for use in applications where the current flowing in each direction needs to be controlled. The TRIAC is a semiconductor device consisting of three terminals: a gate, main terminal MT1, and a main terminal MT2. BTA208S-800F is a high-performance TRIAC mainly designed for the safety applications.TRIACs are typically used in the power control of AC circuits in household appliances, such as microwave ovens, dimmers for stage lighting and motor speed control. In addition, thanks to its fast switching feature, TRIACs are used in various AC switching applications.BTA208S-800F is a two-quadrant TRIAC with an 800V long-distance gate trigger rating that can be operated from AC circuits. The device has very low losses and its internal resistance between MT1 and MT2 is very low, making it ideal for applications with extreme power requirements.BTA208S-800F is mainly used in the fields of safety, industrial motor control, AC motor speed control, lighting, heating and AC neutral line protection. The device provides a fast switching time and a high commutation capability, thus making it ideal for AC load switching control.The working principle of BTA208S-800F is that the main terminals MT1 and MT2 act as a direct current (DC) path and the gate acts as an AC control terminal. The device is triggered when the gate terminal receives an appropriate amount of AC current. When the gate current is below the level set by the device’s manufacturer, the device is off. Above that level, the device is on and current can flow from MT1 to MT2.The BTA208S-800F can also be triggered from both MT1 and MT2 terminals directly, depending on the applied voltage. When both MT1 and MT2 voltages are greater than the rating of the device, the device turns ON. When both MT1 and MT2 voltages are lower than the device’s rating, the device turns OFF.In summary, BTA208S-800F is a high-performance TRIAC mainly designed for safety applications. The device has very low losses and a fast switching time, making it ideal for AC load switching control. It is mainly used in the fields of safety, industrial motor control, AC motor speed control, lighting, heating and AC neutral line protection.
