Rules of thumb like that are almost useless. It would GREATLY depend
upon the type of semiconductor. MOS memory would be pretty vulnerable,
while bipolar power rectifiers would be very much less so.
In some cases, it takes energy (mostly current) to be destructive. In
other cases, voltage spikes with almost negligible current can be killers.

One reference I found stated the "kill radius" for electronics
(semiconductors) is 300ft from a primary strike. The same radius for
a person is 50ft. Presumably the ground voltage gradient, the
capacitive charging/discharge, surface arc paths, and/or the induced
currents are sufficient in both cases to cause damage or serious
injury/fatality. Livestock are more vulnerable given their wider
footprint.
