DESCRIPTION
RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The RClamp series has been specifically designed to protect sensitive components from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), EFT (electrical fast transients), and lightning. The RClampTM7002M 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 capacitance of only 10pF and may be used to protect two high-speed lines without sacrificing signal integrity. 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.
