PESDxV4UG series
Very low capacitance quadruple ESD protection diode arrays
7.
Application information
The PESDxV4UG series is designed for protection of up to four unidirectional data lines
from the damage caused by ESD and surge pulses. The PESDxV4UG series may be
used on lines where the signal polarities are above or below ground. The PESDxV4UG
series provides a surge capability of 16 W per line for an 8/20
μ
s waveform.
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 PESDxV4UG as close to the input terminal or connector as possible.
2. The path length between the PESDxV4UG 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.
