Working Principle of BTA312-600D,127

BTA312-600D, 127 works based on the principle of a transistor-controlled thyristor, or TRIAC. A TRIAC is formed by three terminals, namely the Main Terminal (MT), the Gate Terminal (GT) and the Auxiliary Terminal (AT).The principle of operation of the BTA312-600D, 127 involves the passage of current through the Main Terminal and then turning the switch on by providing a control voltage at the Gate Terminal. This begins the conduction of current in both the directions between the MT and AT. The BTA312-600D, 127, in addition to its two other terminals features a breakdown voltage of 650 V, maximum junction temperature of 175° C and a continuous current of 12 A. Moreover, the device is equipped with anti-parallel diodes. These diodes help in carrying the current if the TRIAC is connected in parallel and it is in blocking state.In conclusion, the BTA312-600D, 127 is a content of the family of TRIACs, mainly used for the control of larger AC loads. The device is widely applicable and its working principle involves the passage of current through the Main Terminal and then turning the switch on by providing a control voltage at the Gate Terminal.
