DIODE REVERSE RECOVERY TIME-I

Now let’s analyze that what would happen when we change diode state from forward biase from reverse biase. This state change takes time which is known as reverse recovery time. Consider the following circuit of diode to analyze the switching time of diode.

  

When the diode is in forward biase, the minority charge distribution of diode is as:

And when diode is in reverse biase position, the minority charge distribution is as:

So to change state from forward to reverse biase, the whole minority charge distribution needs to be inverted as we can see from the figures above.
