    Abstract: An electrostatic discharge (ESD) protection device includes a first trigger element and a first silicon control rectifier (SCR) element. The first trigger element has a first parasitic bipolar junction transistor (BJT) formed in a substrate. The first SCR element has a second parasitic BJT formed in the substrate. The first parasitic BJT and the second parasitic BJT has a common parasitic bipolar base, and the first parasitic BJT has a trigger voltage substantially lower than that of the second parasitic BJT.
