Nexperia expands its portfolio of ESD protection solutions for automotive ethernet

February 22, 2022

Nijmegen -- IEEE OPEN Alliance 100BASE-T1 and 1000BASE-T1 compliant Ethernet ESD Protection Devices

Nexperia, the expert in essential semiconductors today announced an expansion to its award-winning portfolio of automotive ethernet ESD protection devices. The three new devices are AEC-Q101 qualified and IEEE OPEN Alliance 100BASE-T1 and 1000BASE-T1 compliant ElectroStatic Discharge (ESD) protection devices designed to protect two bus lines from damage caused by ESD and other transients.

PESD2ETH1GXT-Q, PESD1ETH1GLS-Q and PESD1ETH1GXLS-Q are silicon-based and offer several advantages over alternative ESD protection solutions like varistors. They provide greater reliability, and an improved diode capacitance of 1 pF (max) ensures better signal integrity. Since these ESD protection devices are fully compliant with the IEEE OPEN Alliance 100BASE-T1 and 1000BASE-T1 test specifications which means there is no requirement for customers to perform their own qualification. Under test conditions, they outperform the AEC-Q101 qualification standard by a factor of 2x so customers can be assured to meet the highest automotive quality profile and provide the highest degree of reliability. Their combination of silicon technology and snap back behaviour reduces clamping voltage and residual current when compared to other competing products. These ESD protection devices are available in a choice of the smallest possible leaded (SOT23) and leadless (DFN1006BD-2 / SOD882BD) packages to provide maximum design flexibility. The leadless package has side-wettable flanks which enables automatic optical inspection (AOI), resulting in higher assembly yield.

More information on the new PESD2ETH1GXT-Q (SOT23), PESD1ETH1GLS-Q (DFN1006BD-2) and PESD1ETH1GXLS-Q (DFN1006BD-2) automotive ethernet ESD protection devices including product specifications and datasheets is available at www.nexperia.com/automotive-ethernet-esd-protection
