Protect 10GbE high-speed differential data lines from discharge and surge events

03-10-2019 | Littelfuse | Semiconductors

Littelfuse offers a series of low capacitance TVS Diode Arrays (SPA Diodes) optimised to protect high-speed differential data lines from ESD, CDE, EFT, and lightning-induced surges, keeping network communications reliable by safeguarding signal integrity.


The SP3384NUTG Series can protect up to four channels against up to 15A (IEC 61000-4-5 2nd edition) and up to ±30kV ESD (IEC 61000-4-2) and is offered in a compact μDFN package. The mixture of low capacitance and low clamping voltage make the series a robust protection solution for 2.5G/5G/10G Ethernet high-speed data interfaces with no signal degradation, producing high reliability for a variety of applications.


Typical markets and applications for the series include Datacenter and Telecom, Ethernet, WAN/LAN Equipment, 5G Wireless Backhaul, LVDS Interfaces, Integrated Magnetics, Desktops, Servers and Notebooks.


“Building upon similar footprints in 1GbE and 5GbE applications, the SP3384NUTG expands our portfolio to fill a market need for ultra-strong ESD and surge protection for today’s fastest 10GbE consumer ethernet solutions,” said Tim Micun, director of Business Development, TVS Diode Arrays (SPA Diodes). “It is also packaged in a compact configuration that is familiar to the datacenter, telecom and consumer electronics industries.”
