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.
