The Littelfuse SP3022 series of rugged 0.35pF, 20kV bidirectional (back-to-back) discrete TVS diodes. The device can safely absorb repeated ESD shocks exceeding the maximum level specified in the IEC61000-4-2 international standard without degrading performance.
When AC signals are present, the back-to-back configuration of the SP3022 series can provide symmetrical ESD protection for data lines. Their ultra-low load capacitance (only 0.35pF) makes them ideal for protecting high-speed data lines.
The features of the AEC-Q101 ± 20kV SP3022 series include ultra-low leakage, which can extend battery life; and fast-acting silicon-based ESD protection, which can achieve reliable product realization in the most challenging environments; the company stated that Compared with some existing silicon solutions, it is improved by 15% and compared with alternative technologies, it is improved by 60%.
