Disclosed is an electrostatic discharge (ESD) protection circuit. The ESD protection circuit may include a silicon controller rectifier (SCR) which may be triggered via at least one of its first trigger gate or second trigger gate. The ESD protection circuit may further include a highly doped region coupled to either the anode or cathode of the SCR, wherein the highly doped region may provide additional carriers to facilitate triggering of the SCR during an ESD event, whereby the SCR may be triggered more quickly.

An electrostatic discharge protection apparatus comprises a stack arrangement having a first electrostatic discharge protection element and a second electrostatic discharge protection element. The stack arrangement is arranged to provide a bias potential between the first and second electrostatic discharge protection elements. In one embodiment, the bias potential can be achieved by a clamp arrangement coupled across the stack arrangement.
