Lightning Surge Protection - SP3304N Series
Description
Applications
The SP3304N integrates 4 channels of low capacitance
diodes with an additional zener diode to protect sensitive
I/O pins against lightning induced surge events and
ESD. This robust device can safely absorb up to 20A per
IEC61000-4-5 (t
P
=8/20μs) without performance degradation
and a minimum ±30kV ESD per IEC61000-4-2 international
standard. The low loading capacitance makes the SP3304N
ideal for protecting high-speed signal pins.
Features
• ESD, IEC61000-4-2,
±30kV contact, ±30kV air
• EFT, IEC61000-4-4, 40A
(t
p
=5/50ns)
• Lightning, IEC61000-4-5,
20A (t
p
=8/20µs)
• Low capacitance of 3.5pF
(TYP) per I/O
• Low leakage current of
1µA (MAX) at 3.3V
• 10/100/1000 Ethernet
Interfaces
• Customer Premise
Equipment (CPE)
• VoIP Phones
• Set Top Boxes
• PBX Systems
