Question
Which statement is TRUE regarding DIAC
thyristor.Solution
A DIAC (Diode for Alternating Current) is a semiconductor switching device that is bidirectional and mainly used for triggering TRIACs in AC circuits. Structurally, it has two terminals and consists of three layers of semiconductor material , which allow it to conduct in both directions once the breakover voltage is reached. Unlike a simple diode, it does not conduct immediately in forward or reverse bias, but only after the applied voltage exceeds a certain threshold. This characteristic makes it useful for symmetrical triggering and noise-free operation in AC power control applications.
