Littelfuse SC7520/AQ7520 SPA® TVS Diode Arrays

Littelfuse SC7520 and AQ7520 (Automotive-Grade) SPA® TVS Diode Arrays include eight-channel ultra-low capacitance and high-level ESD protection diodes to protect high-speed data rates such as USB 3.1, DisplayPort, and e-SATA. A typical capacitance of 0.32pF helps ensure signal integrity. These robust devices can safely absorb repetitive ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard (Level 4, ±8kV contact discharge) without performance degradation and safely dissipate 6A of 8/20μs surge current (IEC 61000-4-5 2nd edition).
