Zener has a unique character a work in reverse bias, in contrast with ordinary diodes.


zener more doping at the junction P & N, so that the diode breakdown voltage can be more quickly achieved.


on ordinary diode breakdown voltage will occur hundreds of volts, while the zener breakdown can occur at rates of tens and units of volts.


zener has its own replacement series which consists of diodes, resistors, and voltage source who organized the series.


as a simple zener voltage regulator comprises a voltage source which in pairs with the series resistor & zener mounted parallel with the load.


its function is to keep the load voltage constant or nearly constant, although the load current and voltage source changes.
