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 […]

Temperature effect on diode
The following graph shows the effect of temperature on the characteristics of diode A-B curve: This curve shows the characteristics of diode for different temperatures in the forward biase. As we can see from the figure given above, that curve moves towards left as we increase the temperature. We know with increase in temperature, conductivity […]
Diode: Ideal vs Practical
CHARACTERISTICS OF AN IDEAL DIODE When we talk about the ideal diode, the diode is a device which acts as a short circuit when forward biased and acts as open circuit when reverse biased. Hence the behavior of ideal diode can be shown in the following graph: In forward biased, current is zero till the […]
Diode: Forward Biasing
When we apply voltage across the diode, as shown below: When the voltage applied across the diode is greater than the barrier voltage, the electrons and the holes present in the n-type and the p-type regions of the diode acquire enough energy to cross the barrier at the junction. Now if we talk in […]
