Four-channel TVS diode array combines LDR with enhanced ESD capability

Designed to protect data lines that may experience destructive electrostatic discharge (ESD), Littlefuse has introduced the miniature four-channel bidirectional SP1015 Series TVS diode array (SPA diodes). The robust diodes can safely absorb repetitive ESD strikes (±20kV contact, ±30kV air) well above the maximum level specified in the IEC61000-4-2 international standard without performance degradation. Their bidirectional configuration provides symmetrical ESD protection for data lines when AC signals are present. With just 0.65O of dynamic resistance, the SP1015 Series supports the low clamping voltage needed to protect the small-geometry integrated circuits used in modern electronic devices. Because the SP1015 Series provides four lines of ESD protection in a compact flip chip package, it is ideal for applications where conserving board space is critical, including micro-SIM interfaces, touchscreen controller lines, and general purpose I/Os on smartphones, wearable devices, tablets, and eReaders, says the company. “The SP1015 Series draws upon the technology we developed for the award-winning SP1012 Series TVS Diode Array,” said Tim Micun, product manager for the TVS Diode Arrays line, Littlefuse. “Its compact footprint of less than a square millimetre helps circuit designers economize on both printed circuit board space and cost.”
