What is Zener diode?
[[File:Zener Diode.JPG|thumb|Zener diode]] [[File:Zener diode voltage regulator.svg|thumb|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.<ref>{{cite web |url=http://ocw.weber.edu/automotive-technology/ausv-1320-automotive-electronics/12-diodes/zener-diodes |title=Zener Diode |accessdate=31 May 2012 |archive-date=3 January 2013 |archive-url=https://web.archive.org/web/20130103124809/http://ocw.weber.edu/automotive-technology/ausv-1320-automotive-electronics/12-diodes/zener-diodes |url-status=dead }}</ref> Because it can be built with a known breakdown voltage, it can be used to accurately measure voltage. ==References== {{Commonscat|Zener diodes}} {{Reflist}} [[Category:Electronic components]] {{tech-stub}}
