The OPEN (One-Pair Ether-Net) Alliance Special Interest Group (SIG) is a non-profit alliance of automotive industry and technology providers, who collaborate to encourage a wide scale adoption of Ethernet-based networks as the standard in automotive networking applications. Its work is meant to prepare IEEE and other international standards.

Nexperia is a technical member of the OPEN Alliance SIG, and has developed fully compliant ESD protection devices, based on silicon technology for 100BASE-T1 and 1000BASE-T1 Ethernet. Silicon based ESD protection devices offer a significantly higher performance level of protection - up to 30kV system level robustness – than competing technologies such as varistors.
