What parameter in a germanium diode differs from those in a silicon diode?
A germanium diode has a lower forward voltage drop compared to a silicon diode, typically around 0.3V for germanium and 0.7V for silicon. Germanium diodes also have a higher reverse current leakage compared to silicon diodes.
What are the Characteristics of a silicon diode?
our raight
A silicon avalanche photo diode is fabricated by what process?
A silicon avalanche photo diode is fabricated by the process called impact ionization.
What will be the result if silicon diode is replaced by the germinium diode?
The built is voltage would be lower than silicon diode,more leakage or reverse saturation current,poor thermal stability,high noise and greater conduction in comparison to silicon diodes.
Is 1N4007 OA79 silicon or germanium diode?
The entire 1N40xx series of power diodes are all silicon. The OA79 small signal diode is germanium.
What is the cutting voltage of a silicon diode?
It is not 'Cutting voltage' but it is Cut-in voltage'. It is the voltage at which the diode turns ON. For silicon it is 0.7v. After reaching 0.7V diode current starts increasing rapidly for little increase in voltage.
What is the difference between a germanium diode and a silicon diode?
the cut in vol for silicon diode is 0.7 where as germaium is around 0.3 because of their construction( the ratio of majority n minority carreirs)
What is material made of a zener diode?
SILICON same as any other diode but with different characteristics
How much voltage is there across a silicon diode when it is forward biased?
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
What is the difference between a silicon diode and a germanium diode?
The silicon diode (unless its a Schottky diode) conducts at approximately 0.6 volts. The germanium diode, however, conducts at a much lower voltage, typically 0.2 volts. This means that the germanium diode is better at small signal rectification applications, such as AM radio detectors, allowing a smaller tuner tank circuit.
What is the voltage drop in diode IN4007?
forward drop is the same as any other silicon diode, about 0.7V
What is power diode generally made from?
As that of most power devices power diode are maid from silicon material(because of its wide band gap) . but now days alloy of silicon are used like sic(silicon carbide) by ank
