TVS Diode Arrays (SPA Family of Products) Lightning Surge Protection - SPLV2.8 Series RoHS Pb GREEN SPLV2.8 Series 2.8V 40A TVS Array Description The SPLV2.8 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 =8/20s) with very low clamping voltages.
