Thyristors - TRIACs: BT137-600G0TQ Application Field and Working PrincipleThyristors - TRIACs, essentially a transistor with three terminals, is an electronics-grade device with wide application in various controlling systems. Of those, BT137-600G0TQ, manufactured by Philips Semiconductors, is one of the most popular for its versatility and reliability in various circuits due to its unique features.The device comes in TO-220AB plastic package, and features low thermal resistance, high energy threshold voltage and low gate current trigger. It is a two-quadrant device that can be used in different applications, including switching of loads, steady-state control and phase control applications. Due to its low thermal resistance and its ability to withstand surge up to 8A, variable resistors can effectively be controlled with BT137-600G0TQ.The basic working principle of BT137-600G0TQ is lightning a current by a voltage exceeding a specified threshold, such as in a transformer. Once the current passes through the load, its resistance becomes excessive, thus forming a positive feedback system and maintaining the current.In terms of triggering, BT137-600G0TQ is provided with two gate terminals that can be used to manually turn the device on or off. As the device responds to a relatively low gate current, triggering it to turn on can be done by simply providing a control signal of a few milliamps. The interface provided by the two gate terminals is Bi-directional, meaning that if the device is to be turned off, the current should be reversed and brought to the original state.In conclusion, BT137-600G0TQ is an ideal device for controlling switch in transistor circuits. It is reliable and can be triggered to turn either on or off using a manual control signal. Its low thermal resistance and high energy threshold voltage make it ideal for controlling loads, steady-state control as well as in phase control applications.
