The breakdown voltage or zener voltage v z across the diode remains relatively constant. Three important characteristics of a diode are first of all the forward voltage drop. To Draw The I V Characteristic Curve For P N Junction In Pn Junction Diode And Its Forward Bias Reverse Bias Zener Diode As Voltage Regulator Tutorial Then there is the reverse voltage drop. Diode forward bias characteristics . The relationship of forward voltage and forward current is called the ampere volt or iv characteristic of a diode. When a junction diode is forward biased the thickness of the depletion region reduces and the diode acts like a short circuit allowing full current to flow. Hence the forward current is generated in the circuit. The bias a diode you apply a dc voltage across it. The forward and reverse characteristics of diode of a germanium diode are ...
