ESD protection devices for high-speed automotive interfaces
Devices enable high performance 4-channel ESD protection for automotive multimedia and video link applications offering ideal signal integrity.

Nexperia has announced a new range of ESD protection devices aimed specifically at 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.

As data rates increase and vehicles feature more electric content, the need for EMC protection becomes more critical and providing the correct type of protection is a challenge for design engineers. TrEOS technology from Nexperia 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 latest PESD4USBx series comprises a total of twelve high-performance 4-channel ESD protection devices that incorporate TrEOS technology. 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. All devices 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. This is the highest level of ESD protection currently available in this package size making the devices ideal for modern, densely-packed, automotive designs.
