The Littelfuse SP3022 Series of 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.
