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 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 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 is the difference between a silicon diode and germanium diode?
Silicon diodes have a higher forward voltage drop (~0.7V) compared to germanium diodes (~0.3V). Silicon diodes have higher temperature stability and are more commonly used in modern electronic devices, while germanium diodes are more sensitive to temperature changes and are less commonly used.
What is knee voltage for silicon and germanium?
The knee voltage for silicon is approximately 0.7V, while for germanium it is around 0.3V. The knee voltage is the voltage at which a diode starts conducting significantly.
Compare the characteristics of a silicon and germanium diode?
Potential barrier of silicon is 0.7, whereas potential barrier of germanium is 0.3

What is more referred to use si diode or a ge diode?
Silicon (Si) diodes are more commonly used than germanium (Ge) diodes. Silicon diodes are preferred for most applications due to their higher temperature tolerance, lower leakage current, and greater availability. They are commonly used in rectifiers, signal processing, and various electronic circuits. Germanium diodes, while having some advantages in specific applications (such as lower forward voltage drop), are less common in modern electronics.
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 a substitute for a germanium diode?
There is no exact substitute for a germanium diode, except another germanium diode. However if the only concern is to get a lower forward voltage drop than that of a silicon diode (0.7V), then a schottky barrier diode may be a suitable replacement as its forward voltage drop (<0.1V) is even lower than that of a germanium diode (0.2V).
What type of diode is proper to used silicon and germanium?
A: They both have redeemable quality. Germanium has lower turn on voltage as compared to silicon however their current capability is not too great and also have a problem leaking with temperature. SO THE USE IS DEPENDENT ON APPLICATIONS
How will differentiate silicon and germanium diode from a group of diodes?
Simple, Use the multi-meter , switch to the diode option then connect the positive wire to the positive of diode n negative to the negative ( +ve wire red, -ve wire black) if the there is a reading of =~0.7V then it is silicon. and if it is =~ 0.3V then it is germanium.
What is knee voltage for silicon and germanium?
The knee voltage for silicon is approximately 0.7V, while for germanium it is around 0.3V. The knee voltage is the voltage at which a diode starts conducting significantly.
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.
