technically speaking a Zenner diode is similar to a programmable uni junction transistor or a PUT. what happens is that it has two gates. the programmable gate is attached to a fixed voltage which acts as the threshold voltage. till the time voltage is less than the threshold no current flows. as soon as it reaches the threshold current flows . it does so only on one direction and is hence called a diode. they are generally used in parallel with capacitors for making relays
