Bidirectional TVS diode arrays protects high-speed interfaces

Littelfuse has introduced a series of TVS Diode Arrays (SPA Diodes) designed to protect electronic equipment from destructive ESD. The SP3042 Series bidirectional discrete TVS diode arrays include robust back-to-back TVS diodes fabricated using a proprietary silicon avalanche technology that can safely absorb repetitive ESD strikes up to the maximum level specified in the IEC 61000-4-2 international standard (±30kV contact discharge) without performance degradation. The back-to-back configuration provides symmetrical ESD protection for data lines when AC signals are present in a space-efficient 01005 footprint. The series’ low loading capacitance (0.35pF @ VR=0V, typ.) makes them ideal for protecting high-speed interfaces such as HDMI2.0, USB2.0, USB3.0 and eSATA. Typical applications for the series include ESD protection for high-speed interfaces used in MIPI cameras and displays, DisplayPort1.3, eSATA, IoT modules, smartphones, external storage devices, ultrabook/notebook computers, tablets/eReaders and security modules. “The small footprint of SP3042 series TVS diode arrays allows them to protect high-speed interfaces while occupying minimal space on a printed circuit board,” said Tim Micun, global product manager/TVS Diode Arrays (SPA Diodes) at Littelfuse. “Their low dynamic resistance enables them to respond quickly to prevent ESD damage.”
