WebA diac is a P-N-P-N structured four-layer, twoterminal semiconductor device. MT2 and MT1 are the two main terminals of the device. There is no control terminal in this device. This is just like a triac without gate terminal. The doping level at the two end P-layers is the same. fOperation of a Diac. When T1 is positive,current flow path is p-n ... WebAug 2, 2024 · Triacs and quadracs are useful for ac line frequency power applications such as lighting, motor speed, and temperature controls. Triacs can be driven using dual SCRs or a single diac device. A quadrac is produced by integrating a triac and diac in a single package, reducing component count. In addition to conventional triacs, phototriacs are ...
