Littelfuse, Inc., Chicago, IL, introduces 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 × 0.61mm) flipchip package that would normally contain only one, so it offers a 5x improvement over previous implementations.

By providing the highest number of ESD diodes available in a package less than a square millimeter in size, the SP1012 Series helps circuit designers economize 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 provides industry-leading ESD protection, providing greater than ±15kV protection per IEC61000-4-2 (contact), giving engineers higher end product reliability in the field. It is ideally 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.
