DIODE: Reverse Recovery Time

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 […]

Charge distribution of diode

Normal (un-biased) state: Apply the relation given below                                 n * p = ni2 at constant temperature    (Mass action law) Now we apply the above relation to p-type: p i.e. the concentration of majority carriers (holes) is larger as doping of p-side is high and we have the value of ni2as constant at fixed temperature. Hence from the […]
