This series is not recommended for new designs. Suggests to use SP1004U-ULC-04UTG / SP3420-04UTG commercial series or SESD1004Q4UG-0020-090 automotive grade series for the new designs in near future. SP0524PUTG has been qualified to AEC-Q101 and is appropriate for use in Automotive applications. The SP0524P integrates 4 channels of ultra low capacitance rail-to-rail diodes and an additional zener diode to provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). This robust device can safely absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard (±8kV contact discharge) without performance degradation. The extremely low loading capacitance also makes it ideal for protecting high speed signal pins such as HDMI, USB3.0, USB2.0, and IEEE 1394.
