Abstract
An ESD protection circuit includes a silicon controlled rectifier (SCR) including a first conduction path between a first node and a second node and a clamp circuit coupled to a control terminal of the SCR. The clamp circuit is part of a second conduction path between the first node and the second node. During an ESD event, the clamp circuit conduct an ESD current until a threshold IV point is reached. The clamp circuit triggers the SCR, which then acts as a snapback device to conduct the ESD current at a lower voltage.
