WebOct 2, 2015 · Diac is similar to four-layer diode but it can conduct in both directions meaning it can contact both AC and DC currents. Basic SCR Applications. Basic Latching Circuit. In this circuit a SCR is used to form a basic latching circuit. S1 is a normally open switch and S2 is a normally close switch. When S1 is pushed momentary a small current goes ... WebDiac Operation. Electrically, a diac operates in a manner similar to two zener diodes that are connected in series in opposite directions. The diac is used primarily as a triggering device. This operation is accomplished by the use of the negative resistance characteristic of the diac (current decreases with an increase of applied voltage).
