TVS Diode Array provides five channels of ESD protection in footprint that typically contains only one

Littelfuse has introduced the SP1012 Series TVS Diode Array (SPA Diodes), a miniature, five-channel 6.5pF, 15kV bidirectional TVS array for general-purpose electrostatic discharge (ESD) protection. The SP1012 Series packs five ESD diodes in a 0402-size (0.94mm x 0.61mm) flipchip package that would normally contain only one, so offering a 5x improvement over previous implementations.

By providing a higher number of ESD diodes available in a package less than a square millimeter in size, the SP1012 Series can help circuit designers economise on both printed circuit board (PCB) space and costs. These robust diodes can safely absorb repetitive ESD strikes at the maximum level specified in the IEC61000-4-2 international standard without performance degradation. The bidirectional configuration provides symmetrical ESD protection for data lines when AC signals are present.

The SP1012 Series is configured to protect data lines on flexible PCBs for capacitive touchscreen implementations. Applications include ESD protection for interfaces on wearable technology, smartphones, mobile phones, touchscreen controllers, and SIM cards.

“The SP1012 Series packs a five-line ESD protection solution in a 0402-size footprint, so it’s ideal for those designing products for the growing ‘wearables’ and consumer market,” said Chad Marak, product line director for the SP1012 Series TVS Diode Array line. “A single device can protect five lines against an ESD attack, so it’s well-suited for use on SIM card interfaces and datalines for capacitive touchscreen displays on smartphones and tablets.”
