WebDIAC is two terminal four layer semiconductor device (Thyristors) that can conduct current in either direction, when polarity is active. The basic construction and symbol of DIAC is shown in above diagram. DIAC … WebWhen the voltage is applied, it will not conduct unless the voltage does not exceed the break over voltage V BO or a gate pulse is applied. As we know that TRAIC can conduct for both polarities of applied voltage and it can be triggered by both polarities of gate voltage for either direction. Therefore, the TRAIC can operate in 4 modes.
