TVS Diode Array provides ESD protection for sensitive chipsets.
Press Release Summary:
February 8, 2013 - Optimized for protecting chipsets on high-speed data lines such as USB 3.0 and HDMI, SP3012-06UTG safely absorbs repetitive ESD strikes above maximum level specified in IEC61000-4-2 international standard (Level 4) without performance degradation. Dynamic resistance of just 0.4 Ω lowers clamping voltage for reliable chipset performance in field. Supplied in 3.5 x 1.35 x 0.5 mm µDFN-14 package, product offers 0.5 pF capacitance and lets PCB traces to run directly underneath device.

Provides ESD Protection for Sensitive Chipsets on High-speed Data Lines
Offers Lower Clamping Voltage; Protects USB 3.0 and HDMI Ports on Consumer Electronics
CHICAGO – Littelfuse, Inc., the global leader in circuit protection, today announced it has developed a new SP3012-06UTG Low Capacitance ESD Protection TVS Diode Array (SPA® Devices). The new product is optimized for protecting sensitive chipsets on high-speed data lines from any external ESD (electrostatic discharge) event. Typical applications include USB 3.0 and HDMI port protection on LCD/PDP TVs, DVD/Blu-ray players, desktop PCs, MP3/PMPs, set top boxes, smartphones, ultrabooks/notebooks and digital cameras.
“With a dynamic resistance of just 0.4 ohms, our newest TVS Diode Array can provide a much lower clamping voltage than any competitive device, which helps to ensure reliable chipset performance in the field,” said Chad Marak, Product Manager for Littelfuse TVS Diode Arrays. “It offers the smallest form factor of any six-channel solution in the market today, which is critical for conserving printed circuit board space and simplifying the layout process.”
The SP3012-06UTG offers these key features and benefits:
• Safely absorbs repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard (Level 4) without performance degradation; reduces designer’s dependency on accurate trace impedance simulators
• Ultra low capacitance (0.5pF)
• Market-leading dynamic resistance of 0.4§Ù provides clamping voltage two to three times lower than competitive devices
• ESD, IEC61000-4-2, ±12kV contact discharge, ±25kV air discharge rating
• Small form factor µDFN-14 package (3.5 x 1.35 x 0.5mm); allows PCB traces to run directly underneath the device, minimizing trace discontinuities
• Minimizes signal degradation to preserve system performance while providing robust ESD protection
• Ensures chipset reliability through reduced clamping voltage
• Allows manufacturers to provide ESD protection above IEC standard requirements
• Reduces PCB footprint by more than 50 percent when compared to other fully integrated, 6-channel protection devices
SP3012-06UTG Low Capacitance ESD Protection TVS Diode Arrays are available in quantities of 3,000 in standard tape and reel packaging. Samples are available now for bulk orders; sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit littelfuse.com.
