DIACs

The acronym DIAC is short for “diode for alternating current”. A DIAC is a semiconductor switch that can be turned on in both forward and reverse polarities (full-wave or bi-directional). DIACS are also called "symmetrical trigger diodes".

What is the function of a DIAC?

A DIAC works by introducing a voltage, in either direction. A ’break over point’ is the...
