Semiconductor manufacturer Nexperia has released ESD protection diodes to comply with the OPEN Alliance requirements for use in 10BASE-T1S automotive Ethernet applications.
The diodes feature low capacitance (0.4 pF), which allows them to be used to protect higher-speed applications deploying 100BASE-T1 or 1000BASE-T1 in-vehicle networks while still maintaining high signal integrity.
The diodes offer a single-line ESD protection solution up to 18 kV, according to IEC 61000-4-2, and up to 15 kV with 1,000 discharges. They cover the full range of automotive board net voltages, including 12 V typically found in cars, 24 V for trucks and larger commercial vehicles and 48 V in hybrid and electric cars.
The PESD1ETH10L-Q and PESD1ETH10LS-Q diodes are designed to simplify automotive Ethernet applications, providing a single ESD protection diode that supports both legacy and modern in-vehicle networks.
