Application information Handling data rates up to 480 Mbit/s, USB 2.0 interfaces require ESD protection devices with an extremely low line capacitance in order to avoid signal distortion. With a capacitance of only 1.8 pF, the NXP PRTR5V0U2AX offers IEC 61000-4-2, level 4 compliant ESD protection. The PRTR5V0U2AX integrates two ultra-low capacitance rail-to-rail ESD protection diodes and an additional ESD protection diode in a small 4 lead SOT143B package. The additional ESD protection diode connected between ground and VCC prevents charging of the supply. To achieve the maximum ESD protection level, no additional external capacitors are required.

Application diagram: USB 2.0 Circuit board layout and protection device placement Circuit board layout is critical for the suppression of ESD, Electrical Fast Transient (EFT) and surge transients. The following guidelines are recommended: 1. Place the PRTR5V0U2AX as close to the input terminal or connector as possible. 2. The path length between the PRTR5V0U2AX and the protected line should be minimized. 3. Keep parallel signal paths to a minimum. 4. Avoid running protected conductors in parallel with unprotected conductors. 5. Minimize all printed-circuit board conductive loops including power and ground loops. 6. Minimize the length of the transient return path to ground. 7. Avoid using shared transient return paths to a common ground point. 8. Ground planes should be used whenever possible. For multilayer printed-circuit boards, use ground vias. PRTR5V0U2AX_2 Product data sheet © NXP B.V. 2006. All rights reserved.
