Best Answer

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.

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.


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 is O in oa79 diode?

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

What does OA stand for in OA 79 germanium diode?

It is not "OA 79" it is "0A79", that is the digit zero not the letter "O".The designation of 0A79 is inherited from old designation system for Vacuum Tubes.0 - 0V heater/filament or no heater/filament meaning a Cold Cathode deviceA - Low Current Diode79 - an arbitrary unique number identifying the specific device type, in this case a solid state germanium diode not a vacuum diode or gas diode


Is oA79 diode and oA71 diode are different?

The OA79 is a germanium based diode. This conducts in the forward biased direction at ~0.3Volts. Silicon diodes Conduct in the forward biased direction at ~0.6 or 0.7 volts. If you are wanting to detect weaker signals a germanium diode is a good choice. Nowadays we have good quality low price transistors that can amplify weak signals and the difference between the diodes is not that important in many circuits. Silicon is a very common material so is cheaper than germanium Modern circuits = Good Pre-Amps = Less detection needed. Older Circuits = Pre-Amps not so good = Better detection needed. by chandan EC 3rd year


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.
