Lightning Surge Protection - SLVU2.8 Series
Description
Features
Applications
The SLVU2.8 series was designed to protect low voltage,
CMOS devices from ESD and lightning induced transients.
There is a compensating diode in parallel with the low
voltage TVS to protect one unidirectional line or a high
speed data pair when two devices are paired together.
These robust structures can safely absorb repetitive ESD
strikes at ±30kV (contact discharge) per the 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.
