Product specification
Double ESD protection diodes
in SOT663 package
PESDxS2UQ series
APPLICATION INFORMATION
The PESDxS2UQ series is designed for uni-directional protection for up to two data lines against damage caused by
ElectroStatic Discharge (ESD) and surge pulses. The PESDxS2UQ series may be used on lines where the signal
polarities are below ground. PESDxS2UQ series provide a surge capability of up to 150 W (P
pp
) 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:
Place the PESDxS2UQ as close as possible to the input terminal or connector.
The path length between the PESDxS2UQ and the protected line should be minimized.
Keep parallel signal paths to a minimum.
Avoid running protected conductors in parallel with unprotected conductors.
Minimize all printed-circuit board conductive loops including power and ground loops.
Minimize the length of transient return paths to ground.
Avoid using shared return paths to a common ground point.
Ground planes should be used whenever possible. For multilayer printed-circuit boards use ground vias.
