PESD5V0S2BT

Low capacitance bi-directional double ESD protection diode

7. Application information

The PESD5V0S2BT is designed for the bi-directional protection of 2 lines from the

damage caused by Electro Static Discharge (ESD) and surge pulses. The

PESD5V0S2BT may be used on lines where the signal polarities are above and below

ground. The PESD5V0S2BT provides a surge capability of 130 Watts peak Ppp per line for

an 8/20 µs 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 PESD5V0S2BT as close to the input terminal or connector as possible.

2. The path length between the PESD5V0S2BT 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 group 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.
