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).
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 are the applications of 0A79 diode?
0a79 ( germanium diode )in glass construction form is used in AM detector circuits.
How much voltage is there across a germanium diode when it is forward biased?
About 0.2V
A suitable diode for recitifying weak signals might be made of?
Germanium

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 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 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.
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.
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.
Will a zener diode work the same as a germanium diode?
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
How do you determine the operating parameters of a diode over its full operating range?
Look at the "Diode Markings"
