PESD5V0L7BAS_BS
Product data sheet
The PESD5V0L7BAS and the PESD5V0L7BS are designed for the protection of up to
seven bidirectional data lines from the damage caused by ElectroStatic Discharge (ESD)
and surge pulses. The PESD5V0L7BAS and the PESD5V0L7BS may be used on lines
where the signal polarities are above and below ground.
The PESD5V0L7BAS and the PESD5V0L7BS provide a surge capability of 35 W per line
for a 8/20 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 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
