TVS diode arrays ideal for protecting small chipsets from ESD damage without performance degradation
Littelfuse has introduced a series of 0.9pF ±30kV discrete unidirectional TVS diode arrays (SPA Diodes). The SP3222 Series TVS diode arrays are designed with low capacitance rail-to-rail diodes and an additional Zener diode to provide protection for electronic equipment that may experience destructive ESD. These robust diodes are AEC-Q101 qualified and can safely absorb repetitive ESD strikes above the maximum level specified in international standards without performance degradation.
Low loading capacitance makes them ideal for providing ESD protection for high speed data lines such as MIPI Camera and Display, USB2.0, USB3.0 and eSATA. They are well-suited to protect the newest sensitive chipsets with geometries of 28nm and smaller from destructive ESD.
Additional applications for the arrays include high speed serial interfaces, MHL, DisplayPort 1.3, set top boxes, game consoles, smartphones, external storage devices, notebooks, ultrabooks, tablets and e-readers.
“The SP3222 Series provides extremely low dynamic resistance, which ensures excellent clamping performance across the current profile for better ESD protection,” said Tim Micun, business development manager for TVS Diode Arrays at Littelfuse. “With a let-through voltage no higher than 40V during an 8kV ESD strike, these TVS Diode Arrays provide excellent voltage response, which is particularly important for protecting small, sensitive chipsets.”
