Semtech ESD Solutions for USB 3.0

Semtech ESD Solutions for USB 3.0 safeguard high-speed 3.0 data lines from frequent threats like ESD, EFT, and Cable Discharge events. USB 3.0 ICs require state-of-the-art transient voltage suppression (TVS) protection solutions. These Semtech solutions can arrest dangerous fast rise-time transient threats while also presenting sufficiently low junction capacitance to not adversely impact signal integrity.
