Four-channel rail-to-rail protection for Ethernet and other differential signal lines
It packs four unidirectional channels into a SOT-23-6 package, making it a compact fit for protecting Ethernet PHY-side differential pairs or other multi-line interfaces where board space is tight. With a reverse standoff voltage of 5.5V (max) and a minimum breakdown of 11V, this device sits comfortably on 3.3V or 5V signal rails without loading the line during normal operation. The 100W peak pulse power rating covers ESD events per IEC 61000-4-2 but is not intended for high-energy surge — keep that in mind when the cable runs outside a grounded enclosure. The surface-mount SOT-23-6 footprint is a standard low-profile package, easy to place and reflow without special handling.
That removes one sourcing risk for designs that need a steady, long-term supply of this protection array.
