Nexperia expands ESD portfolio

Nexperia is expanding its portfolio of automotive ethernet ESD protection devices.

The three new devices are AEC-Q101 qualified and OPEN Alliance IEEE 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.

The 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, there is no requirement for customers to perform their own qualification.

Under test conditions, they were shown to outperform the AEC-Q101 qualification standard by a factor of 2x so customers can be assured that they 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.

The 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.
