What is Real Diode? As already mentioned, an actual diode neither behaves as a perfect conductor when forward biased nor as a perfect insulator when reverse biased. When a diode is forward biased, it will…

What is Diode Resistance? What is Diode Resistance? - As already discussed, a forward-biased diode conducts easily whereas a reverse-biased diode restrains the flow of current, so a diode has a low forward resistance as…

Effect of temperature on PN diode characteristics: Temperature on PN diode characteristics is very important consideration in the analysis or design of electronic devices or systems. It affects virtually all of the characteristics of a…

Determination of Diode Characteristics: Determination of Diode Characteristics - The forward characteristics of a diode can be obtained by use of the circuit depicted in Fig. 7.16 (a). The diode voltage is set at a…

Terminal Characteristics of Junction Diodes: The volt-ampere characteristic of a silicon junction diode is depicted in Fig. 7.14. The same Terminal Characteristics of Junction Diodes is depicted in Fig. 7.15 with some scales expanded and…

Quantitative Theory of PN Junction Diode: Quantitative Theory of PN Junction Diode - Here an expression for the total current will be derived as a function of the applied voltage with the assumption that depletion…

Current Components in PN Junction Diode: A Current Components in PN Junction Diode with a forward bias with an external voltage V is shown in Fig. 7.12 (a). Due to forward bias, there exists a…

What is an Ideal Diode - Working and its V-I Characteristics: Diode is a two terminal device that permits only unidirectional conduction. It conducts well in the forward direction and poorly in the reverse direction.…

Breakdown Voltage of PN Junction Diode: When an ordinary P-N junction diode is reverse biased, normally only very small reverse saturation current flows. This current is due to movement of minority carriers. It is almost…
