PROTECTION PRODUCTS - RailClamp
®
Description
RailClamp
®
low capacitance TVS array designed 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
ESD
(electrostatic
discharge),
CDE
(Cable Discharge Events), and
EFT
(electrical fast transients).
The unique design incorporates surge rated, low
capacitance steering diodes and a TVS diode in a
single package. This allows the device to absorb large
amounts of energy while protecting downstream
components from harmful transient events.
The RClamp
®
0504FA is in a 6-pin, SC-70 package. The
leads are finished with lead-free matte tin. They may
be used to meet the ESD immunity requirements of
IEC 61000-4-2, Level 4 (15kV air, 8kV contact dis-
charge). The combination of small size, low capaci-
tance, and high ESD surge capability makes them ideal
for use in applications such as USB 2.0, multimedia
card, and video interfaces.
