oa79 is frequency diode... it pass only the bit of frequency..
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
yes, diode can be used as rectifier diode to convert ac to dc
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
characteristics if gunn 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
0a79 ( germanium diode )in glass construction form is used in AM detector circuits.

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
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

The read type diode are called impatt diode
A diode is used primarily as a Rectifier
Laser diode
