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 trans-

mission 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 capaci-

tance 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 equip-

ment, telecommunication lines, and video lines.
