As data speeds increase and vehicles incorporate more electrical components, the need for EMC protection becomes more critical, and providing the right type of protection is a challenge for design engineers. Nexperia's TrEOS technology optimizes the three pillars of ESD protection—signal integrity, system protection, and robustness—to deliver devices with the ideal combination of low capacitance, low clamping voltage, and high ESD robustness.
The new PESD4USBx series comprises a total of twelve high-performance, 4-channel ESD protection devices incorporating TrEOS technology. Signal integrity is ensured by the extremely low line capacitance of each channel (as low as 0.25 pF) and the line compensation capacitance of less than 0.05 pF. All devices offer deep snapback combined with a low resistance of 0.4 ohms. With ESD protection up to 15 kV, the PESD4USBx series meets IEC61000-4-2 Level 4 and ISO10605 standards. This is the highest level of ESD protection currently available in this package size, making the devices ideal for modern, high-density automotive designs.
They are compatible with a wide range of interface standards, including USB 2.0, high-speed USB up to 10 Gbps, HDMI 2.0, HDBaseT, and the growing number of in-vehicle A/V displays and cameras. PESD4USBx devices also support video links (SerDes): GMSL, FPD-Link, and LVDS.
Designed specifically for automotive applications, the devices exceed the requirements of the AEC-Q101 standard by a factor of two. Furthermore, in Nexperia's latest generation DFN2510D packages (SOT1165D and SOT1176D), side-wettable flanks (SWFs) are available as standard, enabling the use of automated optical inspection (AOI) and thus improving assembly quality for customers.
Commenting on the product launch, Lukas Droemer, Product Manager at Nexperia, stated: “Electronic content is growing rapidly throughout the vehicle, and coupled with the need for high data rates, interfaces commonly found in high-end A/V applications are becoming prevalent. With this high electrical content, vehicles are electrically noisy environments, and these sensitive interfaces require high-performance ESD protection. Our new PESD4USBx series combines robust TrEOS performance with automotive-grade quality specifically for demanding in-car multimedia applications.”.
