Characteristics of Diode (1N4007) Using PSpice

Diode

It is a semiconductor device that converts the sinusoidal signal into uni-direction. In other words, It can also be said that Diode is a semiconductor device that allows the current only in one side and blocks the current in another side.

Working of Diode

Diode works on two mode operation

  1. Forward Biased Mode (FBM)
  2. Reverse Biased Mode (RBM)

Let discuss both modes one by one.

Forward Biased Mode:

Biasing means to apply the dc voltage to diode. It is well known that diode made by PN-junctions. So, when p-type connected with DC positive (+) terminal and n-type connected with DC negative (-) terminal, then Diode said to be in forward biased mode. In this mode, current flows from zero to maximum rating of diode (1N4007). Figure 1 illustrating the connection of diode for forward biased mode operation.

Figure 2 illustrating the waveform result of diode for forward biased mode. As potential barrier for Si diode is 0.7V. When supplied dc voltage increased from 0.7 V, then current starts to flow in forward direction. This can be understood more clearly from figure 2.
