High speed protector in surface mount DFN package. It contains dual, well-matched, low resistance, bidirectional transient current suppressors. By limiting the maximum current to a safe level, this device offers superior protection for very high data rate differential lines against faults caused by short circuits, induction and lightning surges. Typical applications include VDSL and Ethernet ports, protection modules and dongles, process control equipments, test and measurement equipments.
