The SR70 has been optimized for use on ADSL Low capacitance (5pF typical) for high-speed and other high-speed interfaces. interfaces The unique design of the SR70 integrates four surge Low clamping voltage rated, low capacitance steering diodes in a low profile Solid-state silicon-avalanche technology SOT-143 package. It has a typical capacitance of only 5pF and may be used to protect two high-speed lines Mechanical Characteristics without sacrificing signal integrity.
