Littelfuse SP03A Series TVS Diode Arrays Provide Lightning Surge Protection for 1Gb Ethernet Ports
Littelfuse announced the addition of the SP03A Series to its expanding line of TVS Diode Array ( SPA TM family) lightning surge and ESD protection devices. The SP03A is specifically designed for protection of Ethernet and T3/E3 data lines from lightning-induced transients up to a market leading 150A (tP=8/20µs).

The SP03A Series combines the low-voltage TVS with a diode bridge to provide both longitudinal and differential protection in one package. Compared to similar competitive solutions available today, the SP03A-3.3BTG provides the highest peak surge rating with lowest differential capacitance of only 4.5pF. Furthermore, the extremely low dynamic resistance of less than 0.1Ω provides best-in-class clamping performance for sensitive Ethernet PHYs. The SP03A can be used to help manufacturers of telecommunication equipment comply with regulatory standards such as GR-1089, ITU, and YD/T and offer maximum reliability in the field.



The new SP03A Series TVS Diode Array is RoHS compliant and complies with the following standards:



GR-1089 (Intra-Building), 100A, (tP=2/10µs)

Lightning, IEC 61000-4-5, 150A (tP=8/20µs)

ESD, IEC 61000-4-2, ±30kV (contact), ±30kV (air)

EFT, IEC61000-4-4, 40A (tP=5/50ns)
