PESD5V0U2BM
Ultra low capacitance bidirectional double ESD protection array
7. Application information
The PESD5V0U2BM is designed for the protection of up to two bidirectional data or signal
lines from the damage caused by ESD and surge pulses. The device may be used on
lines where the signal polarities are both, positive and negative with respect to ground.

Application diagram
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 PESD5V0U2BM as close to the input terminal or connector as possible.
2. The path length between the PESD5V0U2BM 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
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 PCBs, use ground
vias.
