Diac Characteristics Circuit Diagram. As mentioned earlier the diac has two terminals namely mt1 and mt2 and it can deliver current flow in both directions. Once the capacitor gets charged upto vc then the diac component will start conduction.
When the voltage is passed to the terminals the layer with respective polarity to the voltage gets activated this combination of both the polarities helps in operating the. The above diagram shows the typical construction of the diac. From the diagram a diac unlike a diode resembles a bipolar junction transistor bjt but with the following exceptions.
Otherwise it is damaged.
The characteristics of the diac are very much similar to that of a triac. The characteristics of the diac are very much similar to that of a triac. Mt 2 and mt x are the two main terminals of the device. If the test results conform to the above description the triac is good.
