What is the advantage of silicon diode in other types in changing AC to DC?
Property Germanium silicon Depletion layer 0.15V 0.6V Forward Current milli amperes tens of amperes Reverse leakage micro amperes nano metres Current
IN5408 diode what does it do?
The IN5408 diode is an ordinary silicon diode. It has a 3 amp forward current rating, and a 1000 volt peak reverse voltage rating.
What is the input voltage at which a diode will pass current?
As close to virtually zero volts as is possible: the current will very small but there will be current. This depends on two things: the material that is used to make the diode, and whether the voltage is applied in a forward or reverse direction to the diode. A typical silicon diode will pass forward current above 0.6 V and pass no reverse current until a much higher voltage is applied (check the rated peak inverse voltage PIV)
Why Silicon Controlled Rectifier is called current controlled device?
Because it is controlled by the gate current
What is represented by 'A' in 'OA79' diode?
The symbol 'A' indicates that this device is made from germanium . as you may know germanium has less cut in voltage so this device is used for low power signal or for signal processing. also the leakage current or reverse saturation current of germanium is greater than silicon.
Why multimeter not measuring a peak value?
Reverse saturation current of silicon is in nano ampear therefore it is prefered over germanium

What is the difference of silicon diode and germanium diode?
A silicon diode has a voltage drop of approximately 0.7V, while a germanium diode has a voltage drop of approximately 0.3V. Though germanium diodes are better in the area of forward voltage drop, silicon diodes are cheaper to produce and have higher breakdown voltages and current capabilities.
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.
IN5408 diode what does it do?
The IN5408 diode is an ordinary silicon diode. It has a 3 amp forward current rating, and a 1000 volt peak reverse voltage rating.
Why is the reverse saturation current of germanium diode more than silicon?
Germanium has four number of shells while Silicon has three number of shell. therefore for germanium less energy is required to move the electron from valence band to conduction band if compared to silicon. So at room temperature for germanium their are more number of electrons present in conduction bond hence more number of holes present in the valence energy band. Due to movement of holes reverse saturation current is produced. Their is more number of hole movement in germanium comparatively therefore reverse saturation current is more than silicon for germanium.

Does a silicon diode conduct in reverse bias?
If it's a silicon zener diode, it conducts in the reverse direction after the rated voltage is reached. Otherwise, it only conducts in the forward bias direction.
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.

As close to virtually zero volts as is possible: the current will very small but there will be current.

How much is the reverse breakdown voltage of a 2P4M silicon controlled rectifierct?
hi
What is a true statement about the metalloid silicon?
silicon is a better conductor of electric current than sulfur is.
Why you use silicon not germanium in SCR?
because lekage current of silicon is less than germenium
