SP1050 Series - Power-over-Ethernet PSE Protection
DataSheet:TVS Diode Array SP1050 Datasheet
The SP1050-04BTG provides over-voltage protection for Power-over-Ethernet PSE equipment in a space saving SOIC-8 package. It incorporates 4 TVS Diodes each with their own decoupling capacitor to stabilize power supplies.
The SP1050 is compatible with IEEE 802.3af and IEEE 802.3at requirements while allowing PoE based systems to be protected against damaging threats such as lightning induced surges (IEC61000-4-5), electrical fast transients (IEC61000-4-4), and Electrostatic Discharges (IEC61000-4-2).
The low clamping voltage of 96V makes it compatible with PSE controller technologies.
