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 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 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.


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 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 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 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.


What is the temperature of germanium diode compare to silicon diode?

Germanium diodes typically have a lower forward voltage drop than silicon diodes, which can result in slightly higher temperatures under the same operating conditions. However, the difference in temperature between the two types of diodes is generally minimal and may vary depending on the specific application.


What is O in oa79 diode?

In general O in diodes stands for germanium.since OA79 is a germanium diode O stands for germanium


What is the Difference between Si and Ge diodes?

The significant operational difference between a Si diode and a Ge diode is that Si diodes have a knee voltage of 0.7V needed to allow current flow and Ge diodes have an operational voltage of 0.3V to allow current flow.


Why Si is used than Ge in semiconductor diode?

silicon diodes Cut in voltage is 0.7 V.but the Germanium cut in voltage is 0.3 V that's why .............


If diode is silicon metal then potential difference is 6V and if diode is germanium metal then potential difference is 2V why?

Silicon diodes usually have a voltage drop of .6-.8 volts across them before they will fully conduct. Germanium diodes are usually in the range .5-.6 volts I believe. The voltages you're quoting seem strange - if you can give the setup you're using to measure this, and the part # of the diodes you're using, a better answer can be given. As it stands, I have to ask if you're measuring correctly.


Germanium diode works at 0.3v?

To forward bias a germanium diode you need to reach between 0.2 and 0.3 V between anode (+) and cathode (-). Once this voltage is reached, the diode will conduct. Make sure you have a resistor to limit the forward current to a safe (for the diode, that is) value.
