TVS Diode Array (SPA ® Diodes)
Revision: 12/12/18
Lightning Surge Protection- SP4020 Series
Description
Applications
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 (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.
Features
• ESD, IEC 61000-4-2,
±30kV contact, ±30kV air
• EFT, IEC 61000-4-4, 40A
(5/50ns)
• Lightning, 30A (8/20 as
defined in IEC 61000-4-5
2nd edition)
• Low capacitance of 2.5pF
(@ VR=0V)
• Low leakage current of
0.1μA at 3.3V
• Unidirectional and
Bidirectional configuration
• Small SOD323 package
fits 0805 footprints
• Moisture Sensitivity Level
(MSL-1)
• AEC-Q101 Qualified
• Halogen free, Lead free,
and RoHS compliant
•10/100/1000 Ethernet
•T1/E1/T3/E3
•USB 1.1/2.0
•USB 3.0/3.1
•Power Ports
•Computers and Peripherals
