Quick Detail:
RailClamp® Low Capacitance TVS Diode Array
Description:
RailClamps are surge rated diode arrays designed to protect high
speed data interfaces. The SRDA series has been specifically
designed to protect sensitive components which are connected to
data and transmission lines from overvoltage caused by
electrostatic discharge (ESD), electrical fast transients (EFT),
and lightning.
The unique design incorporates surge rated, low capacitance
steering diodes and a TVS diode in a single package. During
transient conditions, the steering diodes direct the transient
current to ground via the internal low voltage TVS. The TVS diode
clamps the transient voltage to a safe level. The low capacitance
array configuration allows the user to protect up to four
high-speed data lines. The SRDA05-4 may be used to protect lines
operating up to 5 volts while the SRDA12-4 may be used on lines
operating up to 12 volts.
These devices are in a 8-pin SOIC package. They are available with
a SnPb or RoHS/WEEE compliant matte tin lead finish. The high surge
capability (Ipp=25A,tp=8/20μs) means it can be used in high threat
environments in applications such as CO/CPE equipment,
telecommunication lines, and video lines.
Applications:
Transient protection for high-speed data lines to
IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
IEC 61000-4-4 (EFT) 40A (5/50ns)
IEC 61000-4-5 (Lightning) 24A (8/20μs)
Array of surge rated diodes with internal TVS diode Protects four
I/O lines
Low capacitance (<15pF) for high-speed interfaces
Low operating and clamping voltages
