Low-Capacitance Diode Array provides ESD protection to USB 3.0.

Press Release Summary:

Supplied in 3.5 x 1.35 x 0.5 mm µDFN-14 package, SP3011-06UTG presents parasitic capacitance of 0.40 pF that minimizes signal degradation on array's 4 super-speed (5 Gbps) and 2 legacy (480 Mbps) data lines. Each channel also provides Level 4, ±8 kV contact discharge ESD protection. With dynamic resistances of 1.5 W per capacitance, RoHS-compliant product suits electronic devices that use USB 3.0 such as STBs, LCD/PDP TVs, external HDDs, notebooks, desktops, and smart phones.

Original Press Release:

Littelfuse Introduces SP3011 Series, First Device with Fully Integrated ESD Protection for USB 3.0

CHICAGO, IL - Littelfuse, Inc. (NASDAQ/NGS:LFUS) announced the introduction of the SP3011 Series for USB 3.0 ESD protection, a six-channel, ultra-low capacitance diode array packaged in a 3.5x1.35x0.5mm µDFN-14.

The SP3011-06UTG presents an extremely low parasitic capacitance of only 0.40pF, which minimizes signal degradation on the four super-speed (5Gbps) and two legacy (480Mbps) data lines. Furthermore, each channel provides ESD protection at the maximum level specified in the IEC61000-4-2 international standard (Level 4, ±8kV contact discharge).

It is suitable for electronic devices that use USB 3.0 such as set top boxes, LCD/PDP TVs, external hard disk drives, notebooks, desktops, and smart phones. Furthermore, the SP3011 offers one of the lowest dynamic resistances (1.5W) per capacitance of any competitive device.

For more information on dynamic resistance and how to select an ESD device please see www.littelfuse.com/data/en/Application_Notes/Littelfuse-Selecting_an_Appropriate_ESD_Device.pdf

The new SP3011 Series is RoHS compliant and complies with the following standards:

  • ESD, IEC61000-4-2, ±8kV (contact), ±15kV (air)
  • Lightning, IEC61000-4-5, 3A (tP=8/20µs)
  • EFT, IEC61000-4-4, 40A (tP=5/50ns)


    The SP3011 Series is available in tape and reel, 3000 quantity. Contact a Littelfuse sales representative for price and delivery information, or to request samples. For the list of Littelfuse distributors, please visit www.littelfuse.com.
