Diac

Diac is a device which  has di electrode  and as its name suggests it works  on AC.

The cross  sectional view of a diac is shown if the four layers are PNPN and PNPN . the  two terminal of diac are  terminal T1 and T2 the  symbol  of diac is shown in figure  diac is bidirectional device. It can be  switched on either  the positive  cycle  of AC voltage. It is also known as gateless triac.
