ESD protection ICs for automotive and EV applications

Mouser Electronics, Inc. now offers the new PESD1ETH10L-Q and PESD1ETH10LS-Q ESD protection ICs from Nexperia. They comply with the OPEN Alliance requirements for use in 10BASE-T1S automotive Ethernet applications.

The ESD protection devices are fully compliant with the OPEN Alliance IEEE 10BASE-T1s, 100BASE-T1, and 1000BASE-T1 standards, and provide ESD protection up to 18kV (IEC 61000-4-2) that can withstand up to 1000 contact discharges at 15kV, making the devices highly reliable for automotive applications. The devices cover the full range of automotive board net voltages, including 12V, commonly found in cars; 24V for trucks and larger commercial vehicles; and 48V in HEVs and EVs.

The devices also feature a high trigger voltage of 100V and extremely low capacitance (0.4pF), making them excellent for protecting higher-speed applications deploying 100BASE-T1 or 1000BASE-T1 in-vehicle networks, which helps maintain signal integrity. These diodes provide a single-line ESD protection solution with up to 18kV, according to IEC 61000-4-2, and up to 15kV with 1000 discharges, as per OPEN Alliance.

The PESD1ETH10L-Q ESD device is supplied in a compact DFN1006-2 (SOD882) package. The PESD1ETH10LS-Q is housed in a DFN1006BD-2 (SOD882BD) package with side-wettable flanks, allowing visual inspection of solder joints during AOI and improving solder joint reliability.
