Application information The PESDxU1UT series is designed for protection of high-speed datalines from damage caused by ESD and surge pulses. PESDxU1UT devices combine an ESD protection diode and an ultra low capacitance compensation diode to ensure an effective device capacitance as low as 0.6 pF. The PESDxU1UT series provides a surge capability of up to 200 W per line for an 8/20 s waveform. protected data line n.c. 2 1 1 2 3 3 n.c. ground PESDxU1UT PESDxU1UT 006aaa443 Two PESDxU1UT devices in anti-parallel configuration provide ESD protection in a common-mode application.

Rev. 02 -- 20 August 2009 7 of 13 PESDxU1UT series NXP Semiconductors Ultra low capacitance ESD protection diode in SOT23 package 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 PESDxU1UT as close to the input terminal or connector as possible. 2. The path length between the PESDxU1UT 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. PESDXU1UT_SER_2 Product data sheet (c) NXP B.V. 2009. All rights reserved.
