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: Reverse Biasing
When the polarity of the external voltage source is opposite to the above case i.e. when positive terminal is connected to n-side and negative terminal to p-side, then diode is said to be reverse biased as shown below: When we reverse bias the diode, the majority carriers have again 3 types of forces acting on […]
