ESD protection diodes are OPEN Alliance-compliant
Nexperia has released what are believed to be the industry’s first ESD protection diodes to comply with the OPEN Alliance requirements for use in 10BASE-T1S automotive Ethernet applications.
According to the company, the low capacitance (0.4 pF) of these diodes means they can also be used to protect higher speed applications deploying 100BASE-T1 or 1000BASE-T1 in-vehicle networks while still maintaining excellent signal integrity.
The diodes offer a single line ESD protection solution with up to 18 kV, according to IEC 61000-4-2, and up to 15 kV with 1000 discharges, as per OPEN Alliance. 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 is available in a DFN1006-2 package measuring 1.0 mm x 0.6 mm x 0.48 mm while the PESD1ETH10LS-Q is available in DFN1006BD-2 measuring 1.0 mm x 0.6 mm x 0.37 mm with side-wettable flanks to enable automated optical inspection (AOI) in applications that require higher levels of soldering reliability.
The OPEN Alliance (One-Pair Ether-Net) is a non-profit group of automotive manufacturers, technology providers, and suppliers working to establish Ethernet-based networks as the standard for in-vehicle networking. Founded in 2011, the alliance fosters collaboration across the industry to support open access to specifications and advance automotive connectivity.
