RClamp^®3354S
Low Voltage RClamp^®
Surge Protection for GbE Interfaces
PROTECTION PRODUCTS - RailClamp^®
Description
RailClamp^® TVS diodes are specifically designed to
protect sensitive components which are connected to
high-speed data and transmission lines from
overvoltage caused by ESD (electrostatic discharge),
CDE (cable discharge events), and EFT (electrical fast
transients).
The RClamp^®3354S incorporates surge rated, low
capacitance steering diodes and a TVS diode in a single
package. Each device will protect up to four high-speed
lines. The RClamp3354S can withstand a high level of
surge current (25A, 8/20us) while maintaining a low
loading capacitance of less than 5pF. The high surge
capability means it can be used in high threat environ-
ments in applications such as Gigabit Ethernet, telecom-
munication lines, and LVDS interfaces.
The RClamp3354S is constructed using Semtech’s pro-
prietary EPD process technology. The EPD process pro-
vides low stand-off voltages with significant reductions in
leakage current and capacitance over silicon-avalanche
diode processes. It features a low operating voltage of
3.3 volts for superior protection.
The RClamp3354S is in a 5-lead SOT-23 package. The
leads are finished with lead-free matte tin.
