protecting from voltage and current spikes

[jayken]

I need to protect a target pcb from damage from voltage/current spikes coming from a testing unit. Any ideas of how I would go about this?

What kind of voltage / current spikes?

 

[jayken]

transient, as well as more permanent problems such as shorts in the tester unit... board is runing on 3V logic and I don't want that to ever be exceeded.

You need a new tester, period.

Trying to insulate your device from your tester's potential to damage is simply a poor allocation of resources, in addition to potentially obscuring the actual performance of your system under test.

Isn't this the exact same problem you have another thread on one row down?
