PROTECTION PRODUCTS - RailClamp ?
Description
The RailClamp ? series consists of ultra low capacitance
TVS arrays designed to protect high speed data inter-
faces. This series has been specifically designed to
protect sensitive components which are connected to
high-speed data and transmission lines from overvoltage
caused by ESD (electrostatic discharge), CDE (Cable
Discharge Events), and EFT (electrical fast transients).
They are designed for use in applications where board
space is at a premium. Each device requires less than
2.9mm 2 of PCB area and will protect two high speed
data lines.
The monolithic design incorporates surge rated, low
capacitance steering diodes and a TVS diode in a single
package. Each line has a typical capacitance of 0.9pF to
ground and 0.3pF between lines. The capacitance of
each line is well matched for consistant signal balance.
Signal integrity is further preserved with the flow through
design. A connection to the TVS is provided for protec-
tion of external voltage busses, such as those found in
USB applications. This device is optimized for ESD
protection of portable electronics. They may be used to
meet the ESD immunity requirements of IEC 61000-4-2,
Level 4 (±15kV air, ±8kV contact discharge).
The RClamp0502A is in a 6-pin, RoHS/WEEE compli-
ant, SC-89 (SOT-666) package. It measures 1.6 x 1.6
x 0.6mm. The leads are finished with lead-free matte
tin. The small package makes it ideal for use in por-
table electronics such as cell phones, laptops, and
digital still cameras.
