Automotive Qualified High-Performance 4-channel ESD Protection Diodes for High-Speed Interfaces
Nexperia has introduced the PESD4USBx series that includes twelve high-performance 4-channel ESD protection devices. These TrEOS technology-based devices have been designed for protecting the ever-increasing number of high-speed interfaces found in automotive applications, especially the in-vehicle networks (IVN) associated with infotainment and vehicle communications.
The devices offer very low line capacitance for each channel (as low as 0.25 pF) and sub-0.05 pF line matching capacitances for ensuring signal integrity. With up to ±15 kV ESD protection, the PESD4USBx series combines deep snapback with a low resistance of 0.4 Ohm, hence they are suitable for modern, densely packed automotive designs.
The new devices are supported by a wide range of interface standards such as 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. The DFN2510D packages (SOT1165D and SOT1176D), side-wettable flanks (SWF) are available as standard, this allows the use of automatic optical inspection (AOI) for enhancing assembly quality for customers.
