The SL1011A series offers high levels of performance on fast rising transients in the domain of 100V/µS to 1KV/µS, which are
those most likely from induced Lightning disturbances. The
SL1011A 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 5,000A pulse without destruction.
FEATURES
• RoHS compliant
• Low insertion loss
• Excellent response to fast rising transients.
• Ultra low capacitance.
• 5KA surge capability tested with 8/20µs pulse as defined by
IEC 61000-4-5
• 20,000 A single shot surge capability tested with 8/20µs
