Three ESD protection devices extend Nexperia’s automotive Ethernet range
Three additions to Nexperia’s portfolio of ESD protection for automotive Ethernet are AEC-Q101-qualified and OPEN Alliance IEEE 100BASE-T1 and 1000BASE-T1 -compliant. The PESD2ETH1GXT-Q, PESD1ETH1GLS-Q and PESD1ETH1GXLS-Q electrostatic discharge (ESD) protection devices are designed to protect two bus lines from damage caused by ESD and other transients.
The three additions are silicon-based and offer several advantages over alternative ESD protection options, such as varistors, said Nexperia. They provide greater reliability, claimed the company and have an improved diode capacitance of 1pF (max) to ensure better signal integrity. These ESD protection devices comply 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 two, explained Nexperia. In addition, the combination of silicon technology and snap back behaviour reduces clamping voltage and residual current when compared to other competing products. The PESD2ETH1GXT-Q, PESD1ETH1GLS-Q and PESD1ETH1GXLS-Q are available in a choice of small leaded (SOT23) and leadless (DFN1006BD-2 / SOD882BD) packages. The leadless package has side-wettable flanks which enables automatic optical inspection (AOI), resulting in higher assembly yield.
Nexperia produces semiconductors and offers a portfolio which includes diodes, bipolar transistors, ESD protection devices, MOSFETs, GaN FETs and analogue and logic ICs.
Nexperia is headquartered in Nijmegen, the Netherlands. It is a subsidiary of Wingtech Technology.
