TVS Diode Arrays offer layout flexibility via packaging options.

Press Release Summary:

Respectively offered in uDFN-6 and SOT23-6 packages, SP3012-03UTG and SP3012-04HTG protect sensitive chipsets with high-speed data lines from external ESD events (±12 kV min contact, ±25 kV min air). Form factor simplifies PCB layout by allowing traces to run directly underneath device and conserve board space. While clamping voltage promotes reliable equipment performance in field, capacitance of 0.5 pF minimizes signal degradation and distortion. Dynamic resistance is 0.4 Ω.

New Packaging Options for Littelfuse SP3012 Series TVS Diode Arrays Provide Greater Layout Flexibility

Up to 66 Percent Greater Clamping Performance than Other Industry Options

CHICAGO — Littelfuse, Inc., the global leader in circuit protection, has added two new packaging options to its SP3012 Series TVS Diode Array (SPA® Diodes) line. Like the rest of the series, these new devices are optimized for protecting sensitive chipsets with high-speed data lines from external ESD (electrostatic discharge) events. The new SP3012-03UTG (uDFN-6) and SP3012-04HTG (SOT23-6) devices offer board designers more options and greater layout flexibility. They also provide up to 66 percent greater clamping performance than other industry options, ensuring greater chipset reliability.

Typical applications for these new additions to the SP3012 Series include ultrabooks, LCD TVs, set-top boxes, Ethernet switches, etc.

“With a dynamic resistance of just 0.4 ohms, the SP3012-03UTG and SP3012-04HTG provide a much lower clamping voltage than other devices available in the industry, which helps to ensure more reliable equipment performance in the field,” said Chad Marak, Product Line Director, TVS Diode Arrays. “Additionally, their ultra-low capacitance minimizes signal degradation so the design engineer doesn’t have to trade off protection for system performance.”


Ultra-low capacitance of 0.5pF minimizes signal degradation and distortion for high-speed applications such as HDMI 1.3/1.4 and USB 2.0, USB 3.0, DisplayPort, etc.

Very low dynamic resistance of 0.4Ω provides very low clamping voltages to protect sensitive high-speed chipsets.

ESD capability is a minimum of ±12kV (contact), ±25kV (air), which exceeds the highest level of the IEC61000-4-2 standard (Level 4).

Small form factor packages simplify the PCB layout by allowing the traces to run directly underneath the device and save valuable board space.
