Automotive Ethernet ESD Protection Devices

Nexperia has announced an expansion to its portfolio of automotive ethernet ESD protection devices with three new devices that are AEC-Q101 qualified and are designed to protect two bus lines from damage caused by ESD and other transients. The new PESD2ETH1GXT-Q, PESD1ETH1GLS-Q, and PESD1ETH1GXLS-Q devices are silicon-based and provide an improved diode capacitance of 1 pF (max) which ensures better signal integrity. 

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 qualifications. Moreover, the combination of silicon technology and snap back behavior 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 enable automatic optical inspection (AOI), resulting in higher assembly yield.
