Low capacitance TVS diode array’s small footprint is ideal for use in a range of mobile devices

Littelfuse has introduced a new series of small-footprint TVS diode arrays (SPA Diodes) that are optimized for protecting high-speed signal pins. The SP3422-04UTG Series 0.2pF 22kV TVS diode array integrates four channels of ultra-low capacitance rail-to-rail diodes and an additional zener diode to provide protection for electronic equipment that may be exposed to destructive ESD. This robust component can safely absorb repetitive ESD strikes above the maximum level specified in the IEC 61000-4-2 international standard without performance degradation.

“The SP3422-04UTG Series is just one-third the size of a typical four-line array, which permits straight-through routing, eliminating signal integrity issues with fan outs,” said Tim Micun, business development manager/TVS diode arrays at Littelfuse. “Because it combines a small footprint with the lowest loading capacitance available in this format, it’s ideal for use in mobile devices, where board space is at a premium.”
