First USB4 ESD protection device for USB-C designs
Nexperia has launched what it claims is the first ESD protection device dedicated for the USB4 standard.
The PESD2V8R1BSF uses Nexperia’s TrEOS ESD protection technology with active silicon-controlled rectification. This provides capacitance down to 0.1 pF, clamping dynamic resistance down to 0.1Ω and very high robustness against surge and ESD pulses with up to 20A 8/20 µs protection for fast datalines.
The PESD2V8R1BSF comes in a low inductance SOD962 package.
“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,” said Stefan Seider, product manager at Nexperia. “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.”
The TrEOS protection diodes are packaged in a DSN0603-2 (SOD962) package. This widely-used 0603 form factor has a low inductance for faster protection and a reduction of mechanical and thermal stress as the bond wires are replaced by integration into the monolithic circuit.
