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.
