DIAC’s get damaged when voltage of wrong polarity is applied at its terminals.

DIAC’s get damaged when voltage of wrong polarity is applied at its terminals. Correct Answer False

DIAC’s does get damage when voltage of wrong polarity is applied at the terminals. They are bidirectional device, that is they do not have fixed anode and cathode terminals. They work the same even if the polarity is changed.
