Probably not.
From what I have heard/read from others, .[countrycode] TLDs (.us, .de, etc.) may be helpful when making a geo-targeted website (e.g., you only care about traffic in one particular country). My companies/sites are all global / unaffected by region, so haven't tested that personally.
At best the impact of the TLD would be negligible. Pick whatever TLD you actually want not what might-potentially-in-theory-possibly give you a negligible boost. A TLD's impact on usability/branding is way more important than the impact on SEO.
