The SESD Series Enhanced ESD Discrete TVS provides ultra low capacitance unidirectional and bidirectional ESD protection for the world’s most challenging high speed serial interfaces. Ultra low capacitance permits excellent signal integrity on the most challenging consumer electronics interfaces, such as USB 3.1, HDMI 2.0, DisplayPort, and V-by-ONE. Providing in excess of 22kV Contact ESD protection (IEC61000-4-2) while maintaining extremely low leakage and dynamic resistance, offered in the industry’s most popular footprints (0402 and 0201), the SESD series sets higher standards for Signal Integrity and usability.
