Abstract:
A protection device is provided that exhibits a turn on time of order of one nanosecond or less. Such a device provides enhanced protection for integrated circuits against electrostatic discharge events. This in turn reduces the risk of device failure in use. The protection device can include a bipolar transistor structure connected between a node to be protected and a discharge path.
