Nexperia Delivers First ESD Protection Device for USB4

March 09, 2020 by Paul Shepard

Nexperia has announced the PESD2V8R1BSF, industry’s first ESD protection device dedicated for the USB4™ standard with industry-leading RF performance. Of special interest to engineers designing USB4 and Thunderbolt interfaces, the new device uses Nexperia’s TrEOS ESD protection technology with active silicon-controlled rectification.

It delivers a winning combination of extremely low capacitance (down to 0.1pF); extremely low clamping (dynamic resistance down to 0.1Ω) and very high robustness against surge and ESD pulses (up to 20A 8/20 µs for very fast datalines). PESD2V8R1BSF comes 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 -0.21dB at 10GHz and correspondingly low return loss figures of -17.4dB at 10GHz.

“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,” added Seider.

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