Low Capacitance RClamp® ESD Protection for uUSB Interfaces
RailClamp® is a low capacitance TVS array designed to protect high speed data interfaces. This series has
been specifically designed to protect sensitive components which are connected to data and transmission
lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT
(electrical fast transients).
