PESD4USBx Series ESD Protection Devices

The new PESD4USBx series of high-performing 4-channel ESD protection devices by Nexperia offer ideal signal integrity for automotive multimedia and video link applications. There are a total of 12 ESD protection devices in the series that aim to protect the ever-increasing number of high-speed interfaces found in automotive applications, especially the in-vehicle networks (IVN) associated with infotainment and vehicle communications.

These new PESD4USBx series ESD protection devices address the issue of an increase in data rates and the inclusion of a variety of features for more electric content in vehicles. The TrEOS technology-based devices offer signal integrity, system protection, and robustness, which is an ideal combination of low capacitance, low clamping voltage, and high ESD robustness. The signal integrity is ensured by the very low line capacitance for each channel (as low as 0.25 pF) and the sub-0.05 pF line matching capacitance.

Specifically engineered for automotive applications, the devices exceed the needs of AEC-Q101 by a factor of two. All the 12 devices in the series offer deep snapback combined with a low resistance of 0.4 Ohm. With ESD protection up to ±15 kV, the PESD4USBx series meets IEC61000-4-2 level 4 and ISO10605. Besides, a wide range of interface standards are supported including USB 2.0, Superspeed USB at 10 Gbps, HDMI 2.0, HDBaseT, and the increasing number of automotive A/V monitor displays and cameras found in vehicles. PESD4USBx devices also support video links (SerDes): GMSL, FPD-Link, and LVDS.

Besides, in Nexperia’s state-of-the-art DFN2510D packages (SOT1165D and SOT1176D) side-wettable flanks (SWF) are available as standard, allowing the use of automatic optical inspection (AOI), thereby enhancing assembly quality for customers. The new devices are available as samples and in production quantities from the company website.
