7. PROTECT PRODUCTS APPLICATIONS INFORMATION
■ Device Connection options
SES5VD923-2U is designed to protect one data, I/O, or power supply line. The device is unidirectional and may be used on
lines where the signal polarity is above ground. The cathode dot should be placed towards the line that is to be protected.
■ Circuit Board Layout recommendations for Suppression of ESD.
Good circuit board layout is critical for the suppression of ESD induced transients. The following guidelines are
recommended:
Place the TVS near the input terminals or connectors to restrict transient coupling
Minimize the path length between the TVS and the protected line.
Minimize all conductive loops including power and ground loops.
The ESD transient return path to ground should be kept as short as possible.
Never run critical signals near board edges.
Use ground planes whenever possible, for multiplayers printed-circuit boards, use ground vias.
Keep parallel signal paths to a minimum.
Avoid running protection conductors in parallel with unprotected conductor.
Minimize all printed-circuit board conductive loops including power and ground loops.
Avoid using shared transient return paths to a common ground point.
