The device is fully compliant with Open Alliance specifications for 10BASE-T1S, 100BASE-T1, and 1000BASE-T1 Ethernet interfaces. The RClamp10022PWQ delivers robust electrostatic discharge (ESD) protection, exceeding automotive standards with ±15kV contact and ±25kV air discharge protection per IEC 61000-4-2. Its ultra-low capacitance of 0.6pF (max) ensures signal integrity for high-speed automotive networks up to 10Gbps. Qualified to the AEC-Q101 standard, it is built to withstand the demanding conditions of automotive environments.

"As automotive networks evolve to support ADAS, autonomous driving features and infotainment systems, reliable high-speed data transmission becomes critical," said Eric Wentzel, product marketing director, automotive segment, protection products at Semtech. "The RClamp10022PWQ addresses this need by providing robust ESD protection while maintaining signal integrity across multiple Ethernet speeds, from 10Mbps to 10Gbps."

Key features of the RClamp10022PWQ include:- Open Alliance compliant design.- Wide operating temperature range of -40°C to +125°C.- Flow-through package design for simplified PCB layout.- Side-wettable flanks for automated optical inspection.- 1000 contact discharge endurance at ±15kV.
Semtech showcased the RClamp10022PWQ along with its complete portfolio of automotive circuit protection solutions at the upcoming Automotive Ethernet Congress in Munich from February 18 – 20, 2025.
