TVS Diode Array (SPA^®Diodes)

Lightning Surge Protection - SP1050 Series

RoHS

GREEN

SP1050 Series for Power-over-Ethernet PSE Protection

Description

The SP1050-04BTG provides over-voltage protection for

Power-over-Ethernet PSE equipment in a space saving

SOIC-8 package. It incorporates fourTVS 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 in IEC 61000-4-5 2ND Edition, EFTs (electrically

fast transients) as outlined in IEC 61000-4-5, and 30 kV

ESD air and contact discharges as

The low clamping voltage of 96V(Max) makes it compatible

with PSE controller technologies
