First ESD protection device for USB4

16-03-2020 | Nexperia | Subs & Systems

Nexperia has released the PESD2V8R1BSF, claimed to be industry’s first ESD protection device dedicated for the USB4TM standard with industry-leading RF performance. Of particular interest to engineers creating USB4TM and Thunderbolt interfaces, the new device uses the company's TrEOS ESD protection technology with active silicon-controlled rectification. It presents a winning combination of remarkably low capacitance (down to 0.1pF); notably low clamping (dynamic resistance down to 0.1Ohm) and particularly high robustness against surge and ESD pulses (up to 20A 8/20µs for very fast datalines). The device is supplied in the ultra-low inductance SOD962 package.

Comments Stefan Seider, product manager at Nexperia: “To avoid signal integrity issues, the PESD2V8R1BSF ESD protection diode offers extremely low insertion loss figures of -0.21 dB at 10 GHz and correspondingly low return loss figures of -17.4 dB at 10 GHz. The new ESD protection device is suitable for the higher voltage requirements of USB 3.2. This means it can be placed right behind the USB Type-C connector to protect the coupling capacitance as well, while still being backwards compatible to USB3.2.”

TrEOS protection diodes are packaged in the extremely compact, very robust DSN0603-2 (SOD962) package. The advantages of this widely-used 0603 form factor are extremely low inductance for fastest protection and a reduction of mechanical and thermal stress because bond-wires are substituted by integration into the monolithic circuit.
