SLVU2.8 Low voltage unit for Gigabit Ethernet protection Features Peak pulse current : I = 30 A 8/20 s PP Low capacitance : C = 1.5 pF typ Stand-off voltage : V = 2.8 V R Low leakage current : I = 0.2 A Rmax SO-8 package ECOPACK 2 compliant component IEC 61000-4-5 (1kV 42 24 A) compliant at T = 150 C j Complies with the following standards IEC 61000-4-2 level 4 15 kV (air discharge) 8 kV (contact discharge) SLVU2.8-4A1 SLVU2.8-8A1 IEC 61000-4-4 level 4 2 kV - 40 A (5/50 ns) IEC 61000-4-5 level 2 Description 1 kV - 42 The SLVU2.8 series has been designed to protect IEEE 802.3ab and 802.3at compatible on both Ethernet line. Its low capacitance makes it receiver (4 Vmax ) and driver side ( 3.6 Vmax) compatible with Gigabit Ethernet. MIL STD 883G - Method 3015-7 SLVU2.8-4A1 is designed to be compatible with 25 kV (human body model) Gigabiit Ethernet and Gigabit PoE by using two SO-8 packages and can be used on 10/100 Mbps Ethernet by using a single device. SLVU2.8-8A1 is designed to be compatible with Gigabiit Ethernet and Gigabit PoE by using a single SO-8 package. Surge capability is compatible with IEC 61000-4-5 class 2 (1 kV, 42 , 24 A). Packaged in SO-8, the SLVU2.8 is a flow-through design in order to minimize trace inductances. Footprint is in accordance with IPC 7531 standard.
