SLVU2.8中文资料用于千兆以太网保护的低压单元数据手册ST规格书

描述 Description

The 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.
