RClamp2504P & RClamp3304P
PROTECTION PRODUCTS - RailClamp
®
Description
RailClamp
®
is a low capacitance TVS array designed to
protect high speed data interfaces. This series has been
specifically designed to protect sensitive components
which are connected to data and transmission lines from
overvoltage caused by
ESD
(electrostatic discharge),
CDE
(Cable Discharge Events), and
EFT
(electrical fast tran-
sients).
The monolithic design incorporates surge rated, low
capacitance steering diodes and a TVS diode in a single
package. Each line has a maximum capacitance of
< 0.8pF to ground. The capacitance of each line is well
matched for consistant signal balance. This device is
optimized for ESD protection of portable electronics. It
may be used to meet the ESD immunity requirements
of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact
discharge).
The RClamp
TM
2504P and RClamp
TM
3304P are con-
structed using Semtech’s proprietary EPD process
technology. The EPD process provides low standoff
voltages with significant reductions in leakage current
and capacitance over silicon-avalanche diode pro-
cesses. They feature a true operating voltage of 2.5
volts and 3.3 volts for superior protection.
These devices are in a 6-pin, RoHS/WEEE compliant,
SLP1616P6 package measuring 1.6 x 1.6 x 0.58mm.
The leads are spaced at a pitch of 0.5mm and are
finished with lead-free NiPdAu.
