IIRC, a zener diode behaves like a regular diode (i.e. it basically allows current to pass in one direction, but not the other), but its reverse breakdown voltage is much, much lower than a regular ...

The Zener diode is similar to a general-purpose signal diode which consists of a silicon PN junction. It is a special kind of diode in which current is allowed to flow in the forward direction in the ...
