TVS Diode Array 0402 AEC-Q101 ±20 kV SP3022 Series

Littelfuse's SP3022 series offers small form factor design and protects against ESD in space-constrained applications

Image of Littelfuse SP3022 Series DiodeThe SP3022 series of robust 0.35 pF, 20 kV bidirectional (back-to-back) discrete TVS diodes from Littelfuse 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 0.35 pF) makes them ideal for protecting high-speed data lines. Features of the SP3022 series include ultra-low-leakage, which preserves battery life; and fast-acting, silicon-based ESD protection, which allows for robust product implementations in the most challenging environments; 15% improvement over some existing silicon solutions and 60% improvement over alternative technologies.
