Low-Capacitance TVS Diode Array protects high-speed data lines.

Press Release Summary:

Offered in 0201 flipchip or 0402 packages, SP3022 Series comprises 0.35 pF, 20 kV, bidirectional, discrete TVS diodes that safely absorb ESD strikes over max level specified in IEC61000-4-2 without performance degradation. Back-to-back configuration provides symmetrical ESD protection for data lines when AC signals are present, while leakage of <10 nA at MAX VRWM preserves battery life and signal integrity. Dynamic resistance is 0.7 Ω, and ESD capability is ±20 kV contact discharge.

Ultra-Low Capacitance TVS Diode Array from Littelfuse Delivers Clamping Performance and ESD Protection Superior to Other Solutions

Protection for high-speed data lines in compact 0201 flipchip or 0402 package

CHICAGO – Littelfuse, Inc., the global leader in circuit protection, has introduced the SP3022 Series Low Capacitance ESD Protection TVS Diode Arrays (SPA® Diodes). These robust 0.35pF, 20kV bidirectional (back-to-back) discrete TVS diodes can safely absorb repetitive ESD strikes over the maximum level specified in the IEC61000-4-2 international standard without performance degradation. The SP3022 Series’ back-to-back configuration provides symmetrical ESD protection for data lines when AC signals are present. Their ultra-low loading capacitance (just 0.35pF) makes them ideal for protecting high-speed data lines, such as all released versions of HDMI and USB, DisplayPort™, V-by-One™ and  eSATA. They’re also well suited for use in consumer electronics like set-top boxes, game consoles, smartphones, ultrabooks, notebooks, tablets and eReaders.

“With its compact form factors, and ultra-low capacitance the SP3022 Series addresses the protection needs for emerging infotainment subsystems in the automotive market,” said Chad Marak, product director, TVS Diode Arrays (SPA® Diodes). “The SP3022-01ETG, which is AEC-Q101 qualified, offers circuit designers a low-capacitance, enhanced ESD solution for protection in environments that demand high reliability.”

The SP3022 Series TVS Diode Array offers these key benefits:

Ultra-low capacitance of 0.35pF minimizes signal degradation or attenuation for high-speed data, giving engineers more signal margin in their design; ideal for protecting high-speed data lines, such as HDMI 2.0, USB 3.0, USB 3.1 and eSATA.

Low dynamic resistance of 0.7Ω provides more than 30% lower clamping performance than similar solutions, providing better protection for sensitive chipsets.

Extremely low leakage of <10nA at MAX VRWM preserves battery life and signal integrity because excessive leakage can be seen as additive capacitance for a high-speed differential pair.

ESD capability of ±20kV contact discharge allows for robust product implementations in the most challenging environments; 15% improvement over some existing silicon solutions and 60% improvement over alternative technologies.

Small footprint of 0402 (SOD-882 package) and 0201 (flipchip) saves precious board space and simplifies board layout.

Automotive-grade quality ensures maximum reliability in the harshest environments.


The SP3022 Series TVS Diode Array is available in quantities of 10,000 in tape and reel packaging. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
