Lightning Surge Protection - SRV05 Series
Description
Applications
The SRV05 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 ( JEDEC
MO-178) packaging
• LCD/PDP TVs
• Monitors
• Notebooks
• 10/100/1000 Ethernet • Firewire
• Set Top Boxes
• Flat Panel Displays
• Portable Medical
