You do not want to replace diodes with zener diodes. They are not the same type of device, and the design objective is not the same.
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
Zener diode is heavily doped pn junction diode.
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
This is not possible. You must replace the diode.
A zener diode cannot be used as switch.
Usual symbol for diode is with a triangle - looking as an arrow hinged with a vertical line. Arrow head stands for anode for diode and line stands for its cathode. To give the symbol for zener diode we simply replace the vertical line by letter Z which also symbolizes the first designer 'Zener'
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
When the design says 4.9v zener diode that is all I would put. The more complicated an alternative you try the more things that can go wrong. A silicon diode is not the same as a zener diode, and cannot be used to replace a zener, with reasonable expectation that the circuit will continue to operate as designed.
zener diode is a revers bias diode which used for voltage regulation.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
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.
