TVS Diode Arrays (SPA®® Diodes)
Lightning Surge Protection- SLVU2.8-8 Series
SLVU2.8-8 Series 2.8V 30A TVS Array
RoHS
Pb GREEN
Description
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
IEC61000-4-2 standard and can safely dissipate up to 30A
(IEC61000-4-5, tP=8/20μs) with very low clamping voltages.
