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. Features Pinout 8 7 6 5 • ESD, IEC61000-4-2, ±30kV contact, ±30kV air • Low leakage current of 0.1μA (MAX) at 2.8V • EFT, IEC61000-4-4, 40A (5/50ns) • SOIC-8 (JEDEC MO-012) pin configuration allows for protection of all 4 differential pair for 1GbE • Lightning, IEC61000-4-5, 30A (8/20μs) • Low capacitance of 2.6pF per line • AEC-Q101 qualified Applications 1 2 3 4 • 10/100/1000 Ethernet • Analog Inputs • WAN/LAN Equipment • Base Stations • Switching Systems Functional Block Diagram • Desktops, Servers, and Notebooks Pin 1.3.5.7 Pin 2.4.6.8 ©2015 Littelfuse, Inc.
