Minority charge carrier concentration reduces exponentially as seen away from the junction. When the voltage is applied, due to the forward biased condition, the majority carriers of one side move towards the other. They become minority carriers of the other side. This concentration will be more at the … See more Let us just go through the definitions of the time periods discussed. 1. Storage time − The time period for which the diode remains in the … See more There are many applications in which diode switching circuits are used, such as − 1. High speed rectifying circuits 2. High speed switching … See more There are few factors that affect the diode switching times, such as 1. Diode Capacitance− The PN junction capacitance changes depending upon the bias conditions. 2. Diode Resistance− The resistance offered by … See more
