Littelfuse Inc. has announced its SP3022 series low capacitance ESD protection TVS diode arrays (SPA diodes). According to the company, the robust, 20kV bidirectional discrete TVS diodes can safely absorb repetitive ESD strikes over the maximum level specified in the IEC61000-4-2 international standard without compromising performance.

The SP3022 series' back-to-back configuration offers symmetrical ESD protection for data lines when AC signals are present. Their ultra-low loading capacitance makes them ideal for protecting high-speed data lines, such as all released versions of HDMI and USB, DisplayPort, V-by-One and eSATA, indicated Littelfuse. They're also geared for consumer electronics such as set-top boxes, game consoles, smartphones, Ultrabooks, notebooks, tablets and e-readers.


The SP3022 devices boast ultra-low capacitance of 0.35pF that cuts signal degradation or attenuation for high-speed data, giving engineers more signal margin in their design. The series is geared for protecting high-speed data lines such as HDMI 2.0, USB 3.0, USB 3.1 and eSATA. In addition, the devices offer low dynamic resistance of 0.7? that provides more than 30 per cent lower clamping performance than similar solutions, providing better protection for sensitive chipsets, noted Littelfuse.

The TVS diodes flaunt extremely low leakage of The small footprint of 0402 (SOD-882 package) and 0201 (flipchip) claim to save board space and ease board layout. The SP3022 series TVS diode array is available in quantities of 10,000 in tape and reel packaging. Sample requests can be placed through authorised Littelfuse distributors worldwide. Automotive-grade quality ensures maximum reliability in the harshest environments, added the company.
