What are the applications of 0A79 diode?
0a79 ( germanium diode )in glass construction form is used in AM detector circuits.
What is a 0A79 diode?
oa79 is frequency diode... it pass only the bit of frequency..
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
Why diode 0a79 is used in amplitude demodulation?
This is very old germanium diode and nomenclature comes before a standard had been established for semiconductors. They modeled 0A after the vaccum tubes where 0 - zero means 0Volts filament voltage and A meant single diode. Latter , semiconductor nomenclature come where the first number was telling a number of PN junctions followed by N (this is for US), Japanese and Europeans had different naming standards
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is the function of diode what is the function of diode?
A diode is used primarily as a Rectifier
Can diode be used as rectifier?
yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.
What type of diode is used as a variable capacitor?
varactor diode is a correct answer
Is it pn junction diode used as voltage regulator?
zener diode
What type of diode is a HVR-1X4 diode?
It's a high voltage diode, typically used in microwave ovens.
What is the difference between p n junction and zener diode?
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
