Abstract

An electrostatic discharge (ESD) protection device with a high holding voltage is disclosed including at least an ESD clamp coupled to a holding voltage tuning circuit. The ESD clamp may be coupled to the holding voltage tuning circuit through a connection circuit such as a diode. The ESD clamp may be implemented by a first silicon controlled rectifier (SCR) and the holding voltage tuning circuit may be implemented as a second SCR.
