Abstract
Embodiments of an electrostatic discharge (ESD) protection device and a method of operating an ESD protection device are described. In one embodiment, an ESD protection device includes a bipolar transistor device connected between a first node and a second node, a series protection device connected in series with the bipolar transistor device, and a diode device connected between the second node and a third node. A drain terminal of an NMOS device to be protected is connectable to the first node. A body of the NMOS device to be protected is connectable to the second node. A source terminal of the NMOS device to be protected is connectable to the third node. The diode device and the bipolar transistor device are configured to form a parasitic silicon controlled rectifier. Other embodiments are also described.
