Circuit Protection Electronics Engineering Supply Chain Diodes DiodesLITTELFUSE SP3042 Series Bidirectional Discrete TVS Diode Arrays (SPA Diodes) protect electronic equipment from destructive electrostatic discharges (ESD). Devices include robust back-to-back TVS diodes fabricated using a proprietary silicon avalanche technology that can safely absorb repetitive ESD strikes up to the maximum level specified in the IEC 61000-4-2 international standard (±30kV contact discharge) without performance degradation. The back-to-back configuration provides symmetrical ESD protection for data lines when ac signals are present in a space-efficient 01005 footprint. Product’s low loading capacitance (0.35pF @ VR=0V, typ.) helps protect high-speed interfaces such as HDMI2.0, USB2.0, USB3.0 and eSATA. http://littelfuse.com
