Most ICs can handle at least -3000V static discharge. You need to pump about -5000V to start doing real damage. Even LEDs are so robust now days as to take 3X-5X their rated forward voltage as reverse voltage regardless of what their spec sheet says; I make 120V rectifiers from strings of them all the time.

The 3 kV rating is most likely 3 kV on a human body model, which is a small capacitor (few picofarads) with a series resistor. This says nothing about what happens if you charge a large capacitor to 100v and then dump it through as low a resistance as possible into the victim port.

the killers don't do a low-current static discharge; they do high-current through the protection diodes and seriously mess things up. https://www.youtube.com/watch?v=3hbuhFwFsDU
