Nexperia launches ESD protection device for USB4
Nexperia 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.
