Silicon-based OPEN-Alliance-compliant ESD protection for automotive Ethernet

1 min read

Nexperia, a specialist supplier of discrete and MOSFET components and analogue & logic ICs, has launched pioneering silicon-based, OPEN Alliance-compliant ESD protection for 100BASE-T1 and 1000BASE-T1 automotive Ethernet systems.

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.

The organisation's 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.

“By design of the norm, the Nexperia ESD protection solutions PESD2ETH100-T and PESD2ETH1G-T work with any PHY. Our devices provide outstanding robustness at high data rates without showing degradation like other technologies.” said Dr. Jan Preibisch, Application Marketing Manager.
