RCLAMP7002M_10 Datasheet, PDF (1/7 Pages) Semtech Corporation – RailClamp® Low Capacitance TVS Diode Array

PROTECTION PRODUCTS - RailClamp^®
Description
RailClamp^® TVS diode arrays are specifically designed
to protect sensitive components which are connected
to high-speed data and transmission lines from over-
voltage caused by ESD (electrostatic discharge), CDE
(Cable Discharge Events), and EFT (electrical fast
transients). The RClamp^®7002M has been optimized
for use on the next generation of ADSL interfaces.
Their high surge capability makes them particularly
useful in systems that utilize gas tubes as the primary
protection component.
This device integrates surge rated, low capacitance
steering diodes in a small MSOP-10L package. Each
protection diode features a large area junction to
minimize clamping voltage and increase reliability
during high current surges. It has a maximum capaci-
tance of only 10pF and may be used to protect two
high-speed lines without sacrificing signal integrity. The
RClamp7002M may be used on systems operating
from 3.3 to 70 volts. This means that they may be
used in applications that use the Central Office battery
as the main supply.
The RClamp7002M is also designed for easy board
layout by allowing the signal traces to run straight
through the device. The high surge capability, ease of
layout coupled with the low capacitance and clamping
voltage of the RClamp7002M makes it the superior
choice for protecting two high speed lines against high
energy telecommunication surges.
