Lightning Surge Protection - SPLV2.8-4 Series
Description
Features
Applications
The SPLV2.8-4 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.
