Nexperia launches ESD protection device for USB4Nexperia is launching the PESD2V8R1BSF, which is claimed to be the first ESD protection device dedicated for the USB4TM standard with industry-leading RF performance. Of special interest to engineers designing USB4TM and Thunderbolt interfaces, the new device uses Nexperia’s TrEOS ESD protection technology with active silicon-controlled rectification. It delivers a winning combination of very low capacitance (down to 0.1pF), very low clamping (dynamic resistance down to 0.1Ω) and very high robustness against surge and ESD pulses (up to 20A 8/20 us for very fast datalines). PESD2V8R1BSF comes in the ultra-low inductance SOD962 package.

Stefan Seider, product manager at Nexperia comments: “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.”

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.
