Product data sheet
The devices are designed for the protection of up to four unidirectional data or signal lines
from the damage caused by ESD and surge pulses. The devices may be used on lines
where the signal polarities are both, positive and negative with respect to ground. The
devices provide a surge capability of 16 W per line for an 8/20 s waveform each.
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 device as close to the input terminal or connector as possible.
2. The path length between the device 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 (PCB) conductive loops including power and
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 PCBs, use ground
