If this reverse biased voltage across the diode is increased continually, the depletion layer becomes more and more wider. We know what is Zener diode and what is the basic principle of operation of it. The process of ac to dc conversion is called rectification. In a normal diode, the peak inverse voltage is usually pretty high — 50, 100, even 1,000 V. If the reverse voltage across the diode exceeds this number, current floods across the diode in the reverse direction in an avalanche, which usually results in the diode’s demise. This results in the accumulation of charges around the junction, forming a depletion region. Their drawback is that they are current and temperature sensitive, and are noisy. Working Principle of Zener Diode. We can figuratively name it voltage shifting. The zener diode is used in voltage regulator circuits to provide regulated DC voltage. Depends on your application.

Zener diodes are normal PN junction diodes operating in a reverse-biased condition. The breakdown voltage of Zener diodes will be constant for a wide range of current. When a negative cycle of signal comes across diode it operates in forward biasing condition restrict the negative part of the signal to -0.7 V. For the positive signal diode, D2 is operating as Zener limiter and Di is forward biasing. The Zener diode continue the voltage regulation till reaches its lowest value I. Hence a negative temperature coefficient diode is used for compensation. When we analyze the zener diode curve, we can see that when the voltage applied to the diode is increasing (negatively), the flowing current does not increase a lot. The supply voltage Vs and the resistance Rs are so designed that the diode operates in breakdown region. As the applied reverse voltage tends to increase that result in the increment of the width of the depletion region.
