Zener diode is used as a shunt voltage regulator for regulating voltage across small loads. The point at which the zener voltage triggers the current to flow through the diode can be very accurately controlled (to less than 1% tolerance) in the doping stage of the diodes semiconductor construction giving the diode a specific zener breakdown voltage, ( vz ).
