Nexperia has created ESD protection diodes for 48V vehicle communications networks. “Until now, automotive equipment manufacturers lacked suitable ESD protection solutions specifically designed for 48V data lines,” claimed Nexperia head of protection devices Alexander Benedix. “As a result, they often had to rely on workarounds – either including an additional 12 V power rail or connecting several lower-voltage protection diodes ...

Nexperia is claiming a first for an ESD protection diodes compliant to Open Alliance requirements for 10BASE-T1S automotive Ethernet – a member of the ‘single-pair Ethernet’ family. “The exceptionally low capacitance – 0.4pF – of these diodes means they can also be used to protect higher speed applications deploying 100BASE-T1 or 1000BASE-T1 in-vehicle networks while still maintaining signal integrity,” according ...

Cortec has created packaging paper that is both anti-static and anti-corrosion, positioning it as a replacement for plastic bags. The paper is recyclable and re-pulpable, and does not contain nitrites, phosphates, silicates or hazardous compounds. “This product eliminates static electricity build-up through the use of a coating made from soybean oil,” according to the company. “EcoSonic ESD Paper performs better ...

Nexperia is aiming at protecting high-speed automotive data lines with ESD protection diodes whose capacitance is as low as 0.28pF. With stand-off voltages in the 18 – 32V range and a snap-back characteristic, the AEC-Q101 (automotive) qualified parts are intended to be used close to connectors on boards. The base part number is PESDxxVF1Byy-Q, with xx representing the nominal stand ...

Nexperia is aiming at protecting USB 3.2, HDMI 2.0 and LVDS data lines in vehicles with family of ESD (electrostatic discharge) protection diodes. “Additionally, this portfolio also aims to address the upcoming high-speed video-links as well as the Open Alliance multi-Gbit Ethernet applications”, according to the company. All variants come in 1 x 0.6 x 0.5mm leadless packages to improve ...

The sheer volume of automotive electronics in today’s cars is dramatically driving up the transmission requirements and data payload on automotive networks, writes Lukas Droemer of Nexperia. To take the next step we need high-speed, high-bandwidth Automotive Ethernet. And that means getting the right ESD protection in place to ensure it is both safe and secure while we are driving. ...

Nexperia is aiming at protecting USB4 with a pair of semiconductor clamping chips – effectively back to beck Zeners, but built around active silicon-controlled rectification. “Since there are tight budgets on insertion loss and return loss for the USB4 Super Speed lines, Nexperia is offering devices that minimise the impact of ESD protection on the total budget,” said Nexperia product ...

Amazing Microelectronic of Taiwan has introduced a low-capacitance ESD protection array for data and audio interfaces. “The multifaceted AZ1015-02N maintains low surge clamping voltage for ESD/EOS  protection and low capacitance to keep signal integrity,” according to New Yorker Electronics, which is stocking the part. “The device is used for audio interface, monitor and flat panel display, USB2.0 and SIM ports.” ...

Nexperia has announced a range of ESD protection devices aimed at protecting high-speed interfaces in automotive applications, especially in-vehicle networks for infotainment and communications. There are 12 four-channel devices in the PESD4USBx series, according to the company, with headline figures of  0.25pF line capacitance, <0.05pF line matching and 0.4Ω dynamic resistance. That said, only eight devices show up in the ...

Protecting USB and HDMI connections in commercial and automotive applications is the aim of Vishay’s VBUS05M2-HT5 bidirectional symmetrical (BiSy) two-line ESD protection diode. Supplied in a 1 x 1.1 x 0.45mm DFN1110-3A package with wettable flanks for automated optical inspection, it typically offers only 0.37pF of additional load (0.45pF maximum). “Due to its short leads and small package size, the diode’s ...
