7. 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 to200 W per line for an 8/20 µs waveform.

Two PESDxU1UT devices in anti-parallel configuration provide ESD protection in a common-mode
application.
The two PESDxU1UT devices should be connected as follows:
protected data line is connected todevice 1 / pin 2
device 2 / pin 1
Ground is connected todevice 1 / pin 1
device 2 / pin 2
pin 3 is not connected for both devices

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 beminimized.
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-circuitboards, use ground vias.
