Operating Principle of Thyristor - TRIACs

A Thyristor is a three-terminal device that can either be used to control AC power, or as a switch for DC power. As a switch for AC power, the Thyristor is commonly referred to as a TRIAC. A TRIAC is composed of two separate PN junctions that are combined to form a reverse blocking thyristor, capable of controlling small voltages and currents. The TRIAC comprises of two sections: a bottom section, known as the main terminal, which is composed of a PN junction and a top section, known as the gate terminal, which is composed of a gate lead. The gate terminal controls the main terminal in a manner which allows the main terminal to switch either the positive or negative semiperiod of the AC cycle. The principle of the TRIAC is based on the principle of reverse polarity blocking; the gate lead can block the main terminal from conducting current in a direction which would further increase the current flow, or in other words, reverse polarity. This principle allows the TRIAC to efficiently control and switch AC power.The BT1306-400D,412 is a two-sectioned thyristor, or a TRIAC, which is capable of controlling small AC powers in a range of industrial and consumer applications.
