The SL1011B series offers high levels of performance on fast ris-
ing transients in the domain of 100V/
S to 1KV/S, which are
those most likely from induced Lightning disturbances. The
SL1011B series also features ultra low capacitance (typically 1pF
or less) making them ideal for the protection of high-speed
transmission equipment. These devices are extremely robust and
are able to divert a 10,000A pulse without destruction.
