Point Contact Diode Construction and Working: The point contact diode is basically constructed by touching a metallic whisker to an exposed surface of an N-type semiconductor substrate. The semiconductor used in the point contact diode…
Tunnel Diode Construction and Working: Tunnel Diode Construction and Working - The tunnel diode (sometimes called the Esaki diode after its inventor, Dr. Leo Esaki) is a high conductivity, heavily doped two-terminal P-N junction. This…
Zener Diode Application: Zener diodes have numerous applications in transistor circuitry. Some of their common Zener Diode Application are explained below. 1. Zener Diode as a Voltage Regulator: Voltage regulation is a measure of a circuit's…
Construction and Working of Zener Diode: Zener diode, also sometimes called the breakdown diode, is a P-N junction diode specially designed for operation in the breakdown region in reverse bias condition. Construction and Working of…
PN Junction Diode Applications: An ideal PN Junction Diode Applications is a two terminal polarity sensitive device that has zero resistance (i.e., diode conducts) when it is forward biased and infinite resistance (i.e., diode does…
Switching Diode in Electronics: In discussing the rectifier diodes, the importance of reducing the reverse-bias current and the power losses under forward bias to the minimum was emphasized. But in case a junction diode is…
PN Diode Switching Times: A P-N junction diode may be used as an electrical switch. The electrical circuit can be made 'on' and 'off' by forward biasing or reverse biasing the diode. In both the…
Equivalent Circuit of a Diode: It is usually advantageous to replace a device or system by its equivalent circuit. An equivalent circuit of a device or a system is a combination of electric elements properly…
Transition and Diffusion Capacitance: Transition and Diffusion Capacitance - Electronic devices are inherently sensitive to very high frequencies. Most shunt capacitive effects that can be ignored at lower frequencies due to very high reactance (XC…
Diode as a Circuit Element: Diode as a Circuit Element - The P-N junction diode is considered as a circuit element. One of the most important application of diode is in rectification (i.e., in conversion…
