Mouser is now stocking the SP1012 TVS diode array from Littelfuse - one of the first general-purpose electrostatic discharge (ESD) protection devices of its kind to pack five ESD diodes inside a flip-vhip (FCiP) package - a 5x improvement over previous implementations. The miniature, five-channel bidirectional TVS array is one of the most densely designed ESD protection devices available, helping developers reduce printed circuit board (PCB) space and costs due to its small 0402-size square millimetre footprint. The device provides circuit protection by safely absorbing repetitive ESD strikes at the maximum level (Level 4) specified in the IEC 61000 4 2 international standard without any performance degradation. The bidirectional configuration provides symmetrical ESD protection for data lines when AC signals are present. This diode array provides greater than ±15kV protection per the IEC61000-4-2 international standard, giving developers higher product reliability. For electrical fast transient (EFT) ratings, the SP1012 is specified at 40A (5/50ns) per the EC61000-4-4 international standard. The device is also co-terminated, permitting flexible ground pad layout. The SP1012’s very low 0.48 ohms dynamic resistance supports the low clamping voltages needed for protecting modern-day electronics. The SP1012 features a capacitance of 6.5pF with bidirectional polarity, while offering a nominal 6V standoff voltage. This provides protection on 95% of both current and future user interfaces. The device has an operating temperature of -40C to +125C and its FCiP package fits 0402 footprints.
