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…
Diode Failure Modes and Causes: We would certainly like for solid-state components to be 100% reliable but this is unfortunately not true. All solid-state devices have a certain probability of…
Cold Cathode Gas Filled Diode: The cutaway view of a Cold Cathode Gas Filled Diode is shown in Fig. 5.24. It essentially consists of two electrodes, namely cathode and anode,…
What is Vacuum Diode, Construction, Working and Applications: Construction of Vacuum Diode - Vacuum diode is the simplest form of the electron tube for the production and control of free…
Tunnel Diode Parallel Amplifier Circuit: For operation as an amplifier, a tunnel diode must be biased to the center of its negative resistance region. Figure 21-17(a) shows the basic circuit…
Tunnel Diode Operation and Characteristics: Tunnel Diode Operation - A tunnel diode (sometimes called an Esaki diode after its inventor, Leo Esaki) is a two-terminal negative resistance device that can…
Photodiode Operation and Characteristics: Photodiode Operation - When a pn-Junction is reverse biased, a small reverse saturation current flows due to thermally generated holes and electrons being swept across the…
Semiconductor Diodes Articles: PN Junction Diode Working Principle: A PN Junction Diode Working Principle explains about the ability to permit substantial current flow when forward-biased, and to block current when…
