DescriptionThe SLVU2.8 series has been designed to protect
Ethernet line. Its low capacitance makes it
compatible with Gigabit Ethernet.
SLVU2.8-4A1 is designed to be compatible with
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 Ω, 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.
