Zener diode

diode that allows current to flow in the reverse direction at a specific voltage

Zener diode is like a normal diode, but instead of being destroyed by a big reverse voltage, it lets electricity through. The voltage needed for this is called the breakdown voltage or Zener voltage.[1] Because it can be built with a known breakdown voltage, it can be used to accurately measure voltage.
