Diac – Working and Application Circuits

Last Updated on May 20, 2026 by Swagatam 2 Comments

Diac bidirectional breakover characterictics

The diac is a two-terminal device having a combination of parallel-inverse semiconductor layers, which allows the device to be triggered through both directions regardless of the supply polarity. Diac Characteristics The characteristics of a typical diac can be seen in the following Figure, which distinctly reveals the presence of a breakover voltage in across both […]
