The DIAC (diode for alternating current) is a diode that conducts electrical current only after its breakover voltage, VBO, has been reached momentarily. Three, four, and five layer structures may be used. Behavior is similar to the voltage breakdown of a triac without a gate terminal. When breakdown occurs, internal positive feedback (impact ionization or two t… WebFeb 24, 2012 · A DIAC is a diode that conducts electrical current only after its breakover voltage (V BO) has been reached.
