Zener diode
Switching and symbol (resistor and zener diode)
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.
