Description
The SLVU2.8-4 was designed to protect low voltage,
CMOS devices from ESD and lightning induced transients.
There is a compensating diode in series with each low
voltage TVS to present a low loading capacitance to the
line being protected. These robust structures can safely
absorb repetitive ESD strikes at ±30kV (contact discharge)
per IEC61000-4-2 standard and each structure can safely
dissipate up to 40A (IEC61000-4-5, t_P=8/20μs) with very
low clamping voltages.
Features
• ESD, IEC61000-4-2,
±30kV contact, ±30kV air
• EFT, IEC61000-4-4, 40A
(5/50ns)
• Lightning, IEC61000-4-5,
40A (8/20μs)
• Low capacitance of 2pF
per line
• Low leakage current of
1μA (MAX) at 2.8V
• SOIC-8 (JEDEC MO-012)
pin configuration allows
for simple flow-through
layout
Applications
• 10/100/1000 Ethernet
• WAN/LAN Equipment
• Switching Systems
• Desktops, Servers, and
Notebooks
• Analog Inputs
• Base Stations
