RailClamp
®
low capacitance TVS array is designed 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 to ground.
The internal 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 RClamp
®
3304NA is constructed using Semtech’s
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. The RClamp3304NA
features a true operating voltage of 3.3 volts for
superior protection.
This device is in a 10-pin SLP2626P10 package. It
measures 2.6 x 2.6 x 0.60mm. The leads are spaced
at a pitch of 0.5mm and are finished with lead-free
NiPdAu. The high surge capability (Ipp=25A, tp=8/
20μs) means it can be used in high threat environ-
ments in applications such as Gigabit Ethernet, tele-
communication lines, and digital video.
