SESD Series Ultra Low Capacitance Diode Arrays
1103 DFN array
0802 DFN array
Description
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, the
board space-friendly 0802 DFN and 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.
