Abstract
A device for the protection of an integrated circuit input/output pin against electrostatic discharges includes a first diode between a positive power supply line and an internal connection node for connection to the pin, and a second diode between the internal node and a second negative or zero supply line. The device also includes a protection transistor series-connected between the positive power supply line and the first diode, and a stack of N diodes, where N is equal to one or more, series-connected between the control electrode of the protection transistor and the first diode.
