Bi-curious? Which Direction to Take when Dealing with a TVS

On September 28, 2015 in Circuit Protection by Lynnette Reese

Should my TVS be “unidirectional” or “bidirectional”? I had forgotten. Had someone asked me to guess, I would’ve thought it meant that you should apply bidirectional TVS whenever you know the voltage will go above and below ground. This is sort of right, and definitely applies to protecting circuits that experience AC voltage. But “sort of right” isn’t something I am willing to live with, so I checked it out.
