Zener Diodes

Zener diodes are a type of semiconductor device that has different characteristics from a normal diode. Zener diodes allow current to flow from its anode to its cathode in either a forward or reverse direction, but only when exposed to enough voltage. You can find out more in our Zener diodes guide.
