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 ESD (electrostatic
discharge), CDE (Cable Discharge Events), and Light-
ning.
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 away from
the protected IC. The internal TVS diode clamps the
transient voltage to a safe level. The low capacitance
array configuration allows the user to protect up to two
high-speed data lines.
The RClamp
proprietary EPD process technology. The EPD process
provides low stand-off voltages with significant reduc-
tions in leakage current and capacitance over silicon-
avalanche diode processes. They feature a true
operating voltage of 2.5 volts for superior protection.
The RClamp2502L is in a 8-pin SOIC package. The
leads are finished with lead-free matte tin. The combi-
nation of low clamping voltage, high surge capability,
and low loading capacitance makes the RClamp2502L
an ideal solution for protecting GbE systems to the
lightning immunity requirements of GR-1089.
