Description
The SP4020 components integrate low capacitance
steering diodes with one or two avalanche breakdown
diodes for unidirectional or bidirectional protection,
respectively, to protect against ESD and lightning induced
surge events. These devices can safely absorb up to
30A per IEC 61000-4-5, 2nd Edition (tp=8/20μs) without
performance degradation and a minimum ±30kV ESD
per IEC 61000-4-2 International Standard. The low loading
capacitance and high surge capability make it ideal for
protecting telecommunication ports such as Ethernet and
other high speed data interfaces.
