## What is VI characteristic of a pn junction diode?

Volt-ampere (V-I) characteristics of a pn junction or semiconductor diode is the curve between voltage across the junction and the current through the circuit. Normally the voltage is taken along the x-axis and current along y-axis.

## What is the IV characteristic of pn junction diode?

I-V Characteristic Curve of a Diode When the forward voltage exceeds the diodes P-N junctions internal barrier voltage, which for silicon is about 0.7 volts, avalanche occurs and the forward current increases rapidly for a very small increase in voltage producing a non-linear curve.

What is the VI diode characteristics?

The VI characteristics of PN junction diode in forwarding bias are nonlinear, that is, not a straight line. This nonlinear characteristic illustrates that during the operation of the N junction, the resistance is not constant. The slope of the PN junction diode in forwarding bias shows the resistance is very low.

What is pn junction diode explain the VI characteristics of pn junction under reverse and forward bias?

The VI Characteristics of the PN Junction Diode in Forward Bias. In forward bias condition, the diode gets enough voltage so that it can exceed the value of threshold voltage and provides the carriers with sufficient energy so that it can overcome barrier potential. Hence the forward current is generated in the circuit …

### How many types of VI characteristics are there?

V-I Characteristics of PN Junction Diode Zero bias. Forward bias. Reverse bias.

What is PN junction diode explain the VI characteristics of PN junction under reverse and forward bias?

Which is best fabrication of PN junction?

Diffusion Diode: Diffusion is a process by which a heavy concentration of particles diffuse into a surrounding region of lower concentration.
