TVS diode for protecting USB 3.0 from voltage transients

Infineon has released to the market the new transient suppressing diode for high speed USB3.0 ports. Due to its ability to operate at high speeds the USB 3.0 is sensitive to electrostatic discharge (ESD). To protect the costly equipment/device from ESD, designer choice is to put TVS diode at the pins of ports to snub the unwanted voltage spikes.

The new ESD3v3u4ulc damping diode from Infineon is designed to do that job. ESD3v3u4ulc offers lowest clamping voltage and the lowest dynamic resistance (0.23 ohms), which the Infineon claims as best in the market.. At 20 kV, its ability to absorb energy significantly exceeds the 8 kV called for in the highest industry standard IEC 61000-4-2. Even with the exceptional level of protection it affords, the ESD3v3u4ulc has minimal impact on the signal quality of the high-speed connection says Infineon.

Infineon has packed ESD3v3u4ulc in its advanced TSLP-9-1 package enabling optimum PCB layouts, with a single diode protecting up to four traces simultaneously.
