Infineon Technologies’ ESD3v3u4ulc is a semiconductor diode designed to protect USB 3.0 ports from electrostatic discharge with low clamping voltage and dynamic resistance.
The ESD3v3u4ulc damping diode absorbs energy released through electrostatic discharge on a USB port to protect equipment from damage. At 20 kV, its ability to absorb energy significantly exceeds the 8 kV called for in the highest industry standard IEC 61000-4-2.
Infineon housed the ESD3v3u4ulc in its latest package, the TSLP-9-1, which it says enables optimum PCB layouts with a single diode protecting up to four traces simultaneously.
