Feb 20, 2013 Housed in SOD-323 package that fits 0805 footprint, unidirectional SD05 and bidirectional SD05C protect electronic equipment from damage due to ESD and other transient events. Units offer dynamic resistance of 0.5 and 0.6 Ω, respectively, and can safely dissipate induced surge currents up to 30 A. Unlike ceramic devices, 450 W products are made of silicon diodes which have no inherent wear-out factor. Applications include buttons/keypads, switches, DC power ports, and other low-speed I/Os.

TVS Diode Array provides ESD protection for sensitive chipsets.

Littelfuse, Inc.    Des Plaines, IL 60016
Feb 08, 2013 Optimized for protecting chipsets on high-speed data lines such as USB 3.0 and HDMI, SP3012-06UTG safely absorbs repetitive ESD strikes above maximum level specified in IEC61000-4-2 international standard (Level 4) without performance degradation. Dynamic resistance of just 0.4 Ω lowers clamping voltage for reliable chipset performance in field. Supplied in 3.5 x 1.35 x 0.5 mm µDFN-14 package, product offers 0.5 pF capacitance and lets PCB traces to run directly underneath device.

TVS Diodes offer 600 W peak pulse power dissipation rating.
