Littelfuse has added the SP4061 and SP4062 series to its range of TVS diode arrays for ESD and lightning protection.
The devices are designed to protect high-speed ports such as 10/100/1000 Ethernet and T3/E3 interfaces that may experience damage due to nearby lightning strikes. The SP4061 and SP4062 have standoff voltages of 2,5 V and 3,3 V, respectively, to accommodate the most typical PHY voltages being used today.
Both devices are particularly suitable for protecting Ethernet ports used in PBX systems, VoIP phones, set-top boxes, switches and any other customer premises equipment (CPE). Their robust surge protection and low clamping voltages help equipment manufacturers comply with regulatory standards such as GR-1089, ITU and YD/T.
The new SP4061 and SP062 Series are RoHS compliant and comply with several relevant standards. In addition to elevated ESD protection (±30 kV, contact) and surge capability (20 A, tP = 8/20), the TVS diode arrays offer a low capacitive loading of only 3,5 pF with excellent clamping performance due to their low dynamic resistance of 0,35 Ω and 0,25 Ω, respectively.
