is a bidirectional trigger diode designed primarily for low-voltage triggering in AC control circuits, such as lamp dimmers and motor speed controllers. While modern designs frequently use the
A DIAC (Diode for Alternating Current) is a two-terminal, bidirectional semiconductor device that acts as a voltage-triggered switch. Unlike a transistor, it does not have a control terminal (gate). Instead, it breaks down and conducts current in both directions when the voltage across it exceeds a specific threshold, known as the ( VBOcap V sub cap B cap O end-sub Diac Db2 Datasheet Pdf 14
