This type … See more We now know that a “triac” is a 4-layer, PNPN in the positive direction and a NPNP in the negative direction, three-terminal bidirectional device that blocks current in its “OFF” state acting like an open-circuit switch, but unlike a … See more The Triacis most commonly used semiconductor device for switching and power control of AC systems as the triac can be switched “ON” by either a positive or negative Gate pulse, regardless of the polarity of the AC … See more http://www.learnabout-electronics.org/Semiconductors/thyristors_63.php

TRIAC: What is it? (Definition, Operation & Applications)

WebTriac as a High Power Switch When the switch S is at position 1, the triac is in forward blocking mode and hence the lamp remains in OFF state. If the switch is thrown into position 2, a small gate current flows through the gate terminal and hence the triac is turned ON. What is the symbol of triac? WebBO so that the triac can still be triggered.
