Silicon protection arrays protect electronic devices from destructive ESD

Electronic components distributor Digi-Key Corporation, recognized by design engineers as having the industry’s broadest selection of electronic components available for immediate shipment, today announced it is now stocking SP1000 and SP3000 series silicon protection arrays from Littelfuse.

Part of Littelfuse’s Lead-Free/Green series SPA™ line of silicon protection array products, the SP1000 and SP3000 series are now available for purchase on Digi-Key’s global websites and will be featured in future print and online catalogs.

The SP1000 and SP3000 series of devices protect electronic equipment from electrostatic discharge (ESD) at or above the maximum level specified in the IEC 61000-4-2 international standard (Level 4, 8kV). The SP1000 series offers discrete protection in 0201 and 0402 form factors and also includes multi-channel arrays that vary in capacitance from 3.5-30pF.

The SP3000 series offers multi-channel protection in small form factor packaging with capacitances in the 0.4-2.4pF range. The ultra-low capacitance of the SP3000 series is ideal for preventing signal degradation on today’s high-speed buses such as HDMI and USB 3.0. Both series take advantage of the superior clamping performance of silicon and provide some of the lowest dynamic resistances available today. Applications for the two series include LCD/PDP TVs, set top boxes, notebooks, netbooks, ultra mobile PCs, mobile phones, smart phones, portable navigation devices, portable medical devices, MP3/PMPs, and digital cameras.
