Are you sure it's "burned?"
What do the LED lights do when you power it up? I had a couple Pi2 boards that looked "dead" - but brought them back to life by powering them thru the 3.3VDC GPIO pin (#1), thus bypassing the dead 5V regulator (using a separate 3.3 VDC supply, of course). That supply needs to be fused separately, as well - otherwise, no protection for the SoC.
Although - I'm not a Zero expert. I imagine the Zero is set up the same way as the Pi2 in terms of the regulator? Or not?
