Lightning Surge Protection - SP3050 Series
Applications
The SP3050 integrates low capacitance rail-to-rail diodes
with an additional zener diode to protect each I/O pin
against ESD and high surge events. This robust device can
safely absorb surge current per IEC61000-4-5 (t
P
=8/20µs)
without performance degradation and a minimum ±20kV
ESD per IEC61000-4-2. Their very low loading capacitance
also makes them ideal for protecting high speed signal pins.
Features
• ESD, IEC61000-4-2,
±20kV contact, ±30kV air
• EFT, IEC61000-4-4, 40A
(5/50ns)
• Lightning, IEC61000-4-5,
10A (8/20μs)
• Low capacitance of 2pF
(TYP) per I/O
• Low leakage current of
0.5μA (MAX) at 5V
• Small SOT23-6 packaging
• LCD/PDP TVs
• Monitors
• Notebooks
• 10/100/1000 Ethernet
• Firewire
• Set Top Boxes
• Flat Panel Displays
• Portable Medical
