AQ3045 30kV Bidirectional Discrete TVS Diodes Littelfuse AQ3045 0.35pF, 30kV Bidirectional Discrete TVS Diodes are fabricated in a proprietary silicon avalanche technology to provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). Littelfuse AQ3045 robust diodes 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 and the low loading capacitance makes it ideal for protecting high speed data lines, such as HDMI, USB2.0, USB3.0, and eSATA.
