NEXPERIA PESD2ETH1GXT-Q, PESD1ETH1GLS-Q and PESD1ETH1GXLS-Q are silicon-based semiconductors provide several advantages over alternative ESD protection solutions like varistors. The automotive ethernet ESD protection devices 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. Device’s combination of silicon technology and snap back behaviour reduces clamping voltage and residual current when compared to other competing products. 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.
