The (Diode for Alternating Current) is a bidirectional trigger diode commonly used in power control circuits, such as light dimmers and motor speed controllers. It acts as a switch that stays off until a specific "breakover voltage" is reached, at which point it suddenly conducts current in either direction.
Based on standard industry DIAC datasheets from manufacturers like STMicroelectronics , here are the typical parameters for this series: Breakover Voltage ( VBOcap V sub cap B cap O end-sub diac db2 datasheet pdf 14 top
