2.3.10 TPD2E007

This device is a transient-voltage suppressor (TVS) based electrostatic discharge (ESD) protection device designed to offer system-level ESD protections for a wide range of portable and industrial applications. The back-to-back diode array allows AC-coupled or negative-going data transmission (audio interface, LVDS, RS-485, RS-232, and so forth) without compromising signal integrity. This device exceeds the IEC 61000-4-2 (Level 4) ESD protection and is designed for providing system-level ESD protection for the internal ICs when placed near the connector. The TPD2E007 is offered in 4-bump PicoStar and 3-pin SOT (DGK) packages. The PicoStar package (YFM), with only 0.15mm (maximum) package height, is recommended for ultra space-saving applications where the package height is a key concern. The PicoStar package can be used in either embedded PCB board applications or in surface mount applications. The industry-standard SOT package offers straightforward board layout option in legacy designs.
