Lightning Surge Protection- SP4020 Series
SP4020 Series 2.5pF, 30A Discrete TVS Diode
Description
The SP4020 devices integrate low capacitance steering
diodes with one or two zener 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 IEC61000-4-5 (tp=8/20μs)
without performance degradation and a minimum ±30kV
ESD per IEC61000-4-2 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.
