<p>An electrostatic discharge (ESD) device for protecting an input/output terminal of a circuit, the device comprising a first transistor with an integrated silicon-controlled rectifier (SCR) coupled between the input/output (I/O) terminal of the circuit and a node and a second transistor with an integrated silicon-controlled rectifier coupled between the node and a negative terminal of a supply voltage, wherein the silicon-controlled rectifier of the first transistor triggers in response to a negative ESD voltage and the silicon-controlled rectifier of the second transistor triggers in response to a positive ESD voltage.</p>
