is a Schottky diode on vcc be decent enough?
but what about data line what are my options?
i heard of ADuM3160 but not sure if it also protects data line
i will mostly be working at 5volt

Your topic was MOVED to its current forum category which is more appropriate than the original as it has nothing to do with Installation and Troubleshooting of the IDE
Protect from WHAT exactly? Line surges? USB noise? I/O pins?
A DC to DC approach is best for Vcc (+5 or +3.3 Volts) logic.
Data line protection (ESD) is built into the microcontroller. This is satisfactory for on-board and short off-board connections. For a switch/actuator at a distance from the Arduino, extra protection may be warranted.
