Abstract
A tunable voltage isolation ground to ground ESD clamp is provided. The clamp includes a dual-direction silicon controlled rectifier (SCR) and trigger elements. The SCR is coupled between first and second grounds. The trigger elements are also coupled between the first and second grounds. Moreover, the trigger elements are configured to provide a trigger current to the dual-direction silicon controlled rectifier when a desired voltage between the first and second grounds is reached.
