Forgive if it is a silly question, but I couldn't find any answers to this online. I find it hard to understand some ESD related issues. I believe that, typically, Electrostatic Discharges occur when something electrically charged touches or get sufficiently close to another thing that is grounded (I understand that it doesn't necessarily have to be grounded. I'm talking about common ESD related problems in practice). If this "other thing" is an ESD sensitive component, the electric current that passes through it may damage it.
Assume there is an ESD sensitive component, with no electric charge, in an antistatic bag (isolated from ground?). An electrically charged person opens the bag and touches the component with her bare hands. I presume that, since the component is not connected to ground, no current could pass through it, only to it (assuming some electric charge would flow from the person to the component, until they are at the same potential).
Could this current easily damage a component? Or the electric charge necessary for it to be damaged is too high to be a concern?
Maybe my question is somewhat similar to this one, except it asks about a bird killed by a powerline instead of a component damaged by an electric charged person. The answers mention that a very high voltage would be necessary to kill the bird: Can a bird, previously at earth potential, get electrocuted by landing on a powerline at high-enough voltage due to the initial “equalization charge”?
