Nexperia has extended 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 ESD protection devices created to protect two bus lines from damage induced by ESD and other transients.
PESD2ETH1GXT-Q, PESD1ETH1GLS-Q and PESD1ETH1GXLS-Q are silicon-based and present several advantages over other ESD protection solutions such as varistors. They offer 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, there is no necessity for customers to perform their own qualification. Under test conditions, they outperform the AEC-Q101 qualification standard by a factor of two times, so customers can be assured to satisfy the highest automotive quality profile and offer the highest degree of reliability. Their combination of silicon technology and snapback behaviour lessens clamping voltage and residual current compared to other competing products.
These ESD protection devices are offered 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, enabling AOI, resulting in higher assembly yield.
