An electrostatic discharge (ESD) protection circuit includes a snapback ESD protection device and an ESD tail current clamp circuit. The snapback ESD protection device is configured to shunt current of an ESD event to a voltage reference. The ESD tail current clamp circuit is connected in parallel with the snapback ESD protection device. The ESD tail current clamp circuit is configured to shunt tail current of the ESD event to the voltage reference while the snapback ESD protection device is disabled.
