Electro static discharge protection devices designed to protect two bus lines from damage

Nexperia announces an expansion to 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 electro static 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 1pF (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.
