"The SD05 and SD05C Series are perfect solutions for medical, industrial, consumer, and computing applications for designers who need to 'sprinkle' ESD and/or surge protection around the printed circuit board," said Chad Marak, Director of the TVS Diode Arrays product line. "Their compact SOD-323 package fits right into the footprint of an 0805 MLV, allowing manufacturers to replace them in their designs with a SD05 or SD05C device without requiring a PCB or solder pad change."
Unlike ceramic devices, which have an inherent wear-out factor, SD05 and SD05C Series devices are made of silicon diodes, which allows them to absorb repetitive ESD strikes or surge transients safely without performance degradation. Their low dynamic resistance (0.5Ω for SD05, 0.6Ω for SD05C) provides up to a 50% reduction in clamping voltage when compared with competing technologies, so they can safely dissipate induced surge currents up to 30A.
Typical applications of these devices include buttons/keypads, switches, DC power ports, and various other low-speed I/Os in point-of-sale terminals, test equipment or instrumentation, medical equipment, desktop/notebook computers, servers, computer peripherals, etc.
The SD05 and SD05C Series TVS Diode Arrays are available in quantities of 3,000 in tape and reel packaging. Samples are available now for bulk orders; sample requests can be placed through authorised Littelfuse distributors worldwide.

Will Mg-ion replace Li-ion in rechargeable batteries?
Scientists at the Molecular Foundry used supercomputer simulations to dispel a popular misconception about magnesium-ion batteries that should help advance the technology in the future.
In this platform, TSMC offers multiple processes to provide significant power reduction benefits for IoT and wearable products and a comprehensive design ecosystem to accelerate time-to-market.
