Nexperia delivers first ESD protection device for USB4

Nexperia has announced the PESD2V8R1BSF, said to be the industry’s first ESD protection device dedicated for the USB4 standard.

Of particular interest to engineers designing USB4 and Thunderbolt interfaces, is that the new device uses Nexperia’s TrEOS ESD protection technology with active silicon-controlled rectification.

It delivers a combination of extremely low capacitance (down to 0.1 pF); extremely low clamping (dynamic resistance down to 0.1 Ω) 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.

TrEOS protection diodes are packaged in a very compact and robust DSN0603-2 (SOD962) package. The advantages of this form factor includes: low inductance for faster protection and a reduction in mechanical and thermal stress due to bond-wires being replaced by integration into the monolithic circuit.
