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.

What is the temperature of germanium diode compare to silicon diode?
97f
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 parameter in a germanium diode differs from those in a silicon diode?
germenium diode contains majority electron as a charge carriers while the silicon diode contains holes as a majority charge cariers,
What is the difference between a silicon diode and germanium 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 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 is the temperature of germanium diode compare to silicon diode?
97f
What is more referred to use si diode or a ge diode?
silicon diode is preferred more when compared with germanium diode because in silicon diode the operating voltage is 0.7v where as in germanium diode the operating voltage is 0.3v , germanium is temperature sensitive so it can be easily destroyed by increasing temperature hence silicon diode is preferred more
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 OA in OA79 diode?
In OA79, the letter A stands for rectifier diode and O stands for Germanium. It acts as a point contact germanium diode and also be replaced with 1N4148 depending on the circuit.
Is 1N4007 OA79 silicon or germanium diode?
The entire 1N40xx series of power diodes are all silicon. The OA79 small signal diode is germanium.

Does the material of the diode depends on break down voltage?
A Germanium diode has a much lower breakdown voltage than a silicone diode.
What is OA 79?
i think to make earth feel better visit my blog for more at http://www.jewelryinworld.blogspot.com OA79 represents Germanium diode. O = germanium, A= rectifier diode.
What are the applications of 0A79 diode?
0a79 ( germanium diode )in glass construction form is used in AM detector circuits.
What is meant by 'OA' in OA79 and '1N' in 1N4001?
IN IN = 1N: Refers to the number of junctions (1N= 1 junction). O= Germanium, A= rectifier diode, so OA = germanium rectifier diode.
