Used in conjunction with triacs for simplified gate control circuits or as a starting element in fluorescent lamp ballasts.DIAC is a semiconductor device that has three layers and two junctions. The word DIAC consists of two parts, DI and AC. The DI stands for the diode (or two. Like Di, Tri, Quad, Penta, etc.) and AC stands for Alternating Current. DIAC is the acronym of the diode for alternating current. The DIAC is a combination of two diodes in parallel, one in forward bias and the other one is in reverse bias condition with respect to both sides. DIAC is a specially constructed diode, which allows current to pass in both directions when certain conditions are met.
