The SESD series Ultra Low Capacitance Diode Arrays provides signal integrity-preserving unidirectional ESD protection for the world’s most challenging high speed serial interfaces. Compelling packaging options including the standard 1004 DFN 2.5 mm x 1.0 mm layout, and the board space-friendly 1103 DFN minimize trace layout complexity, and save significant PCB space. The 0402 DFN provides the most flexibility for PCB layout purposes. This series is rated in excess of 20kV contact ESD protection (IEC 61000-4-2) while maintaining extremely low leakage and dynamic resistance, and is offered in the industry’s most progressive and popular footprints. The SESD series sets higher standards for signal integrity and usability
