SP1050 Datasheet Power-over-Ethernet PSE Protection

Manufacturer: Littelfuse

General Description

The SP1050-04BTG provides over-voltage protection for Power-over-Ethernet PSE equipment in a space saving SOIC-8 package.

It incorporates four TVS Diodes each with their own decoupling capacitor to stabilize power supplies.

The SP1050 Series is compatible with the older IEEE 803.
