The SESD Series Ultra Low Capacitance Discrete TVS provides unidirectional and bidirectional ESD protection for the most challenging high speed serial interfaces. Its low off-state capacitance, extremely low leakage (< 50 nA) and low dynamic resistance make it compatible with high speed signaling such as USB 3.1, HDMI 2.0, DisplayPort, and V-by-One®. The SESD series has an ESD (IEC 61000-4-2) rating of ±20 kV packaged in the industry’s popular 0402 and 0201 footprints.
