What is Zener diode function?

Answer 1

Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, aZener diode conducts when the voltage reaches the diode's reverse breakdown voltage.

Answer 2

zener diode is for regulator purpose. it will maintain the constant voltage so we are using as regulator. we have to connect reverse bias then only it will act like zener diode if we are connecting forword bias it will act like normal diode..............

Answer 3

ordinary diodes allows current to pass in only one direction . the ordinary and zener diodes have alot of uses but the only common use for both would be that being able to convert ac current to a Dc current and the zener diodes use only when baised on the reverse voltage break down at a particular reverse voltage it can be used as a voltage regulator

Answer 4

zener iode is a special type of junction diode with different level of doping as compared to normal pn junction diode .... zener diode are used in reguled power supply to provide constant output voltage irrespective of change of input supply or load variations

Answer 5

it is always used in reverse bias the main advantage of zenerdiode is, it is used as a voltage regulator ie;out put voltage will remain constant when input varies

Answer 6

The zener diode is used for rectification and stabilisation.

Answer 7

A: It can be used as a cheap regulator and to save PCB real estate but mostly is used to protect or limit a voltage. Precision zeners however are widely used for references for ADC DAC

Answer 8

As a regulator.
