5~6V is suitable. However, TVS is mainly used for power lines. It is not recommended to use TVS for signal lines.
TVS has a leakage current of several uA to several hundred uA. Therefore, when the impedance of the signal line is high, a voltage drop occurs by the TVS.
If it is a power line, the TVS is protected and the signal line is protected using resistors and diodes as above.
