A RailClamp
to protect high speed data interfaces. This series has
been specifically designed to protect sensitive compo-
nents which are connected to data and transmission
lines from overvoltage caused by electrostatic dis-
charge (ESD), electrical fast transients (EFT), and
lightning.
The unique design incorporates eight surge rated, low
capacitance steering diodes and a TVS diode in a
single package. During transient conditions, the
steering diodes direct the transient to either the
positive side of the power supply line or to ground. The
internal TVS diode prevents over-voltage on the power
line, protecting any downstream components.
The RClamp
The leads are finished with lead-free matte tin. Each
device will protect up to four high-speed lines. They
may be used to meet the ESD immunity requirements
of IEC 61000-4-2, Level 4 (15kV air, 8kV contact
discharge). The combination of small size, low capaci-
tance, and high surge capability makes them ideal for
use in applications such as Ethernet, USB 2.0, and
video interfaces.
