Additional Information Datasheet Resources Samples 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. af and IEEE 802.3at PoE requirements for Mode A or Mode B for both PSE and PD but is not compatible with the new IEEE 802.3bt ( 4 wire-pair simultaneous powering) PSE/PD Class 5 through Class 8 or other 4 wire-pair simultaneous powering schemes that implement independent sources for each two wire-pair interface. It will protect two wire-pair interfaces that share a common grounding from lightning induced surges as outlined i...
