Lightning Surge Protection- SLVU2.8-8 Series
Description
Features
Applications
The SLVU2.8-8 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 IEC
61000-4-2 standard and can safely dissipate up to 30A (IEC
61000-4-5 2nd Edition, tP=8/20μs) with very low clamping
voltages.
