negative tempareture
It depends on the reverse voltage. Up to about 5.6 volts, the zener has a negative temperature coefficient. Beyond 5.6 volts it begins to show a positive temperature coefficient.
zener diode
There are thousands of different zener diode types...use the internet to locate a data sheet for a particular type.
zener diode is a special type of pn junction diode that work in breakdown region . There are two types of brekdowns in zener i.e avlanche breakdown and zener breakdown depending on the doping concentration. A zener diode in an on state can be considered as a voltage source ,equal to its zener voltage n hence act as an voltage regulator
zener diode is a revers bias diode which used for voltage regulation.
to limit the voltage or regulate 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
Zener diode is heavily doped pn junction diode.
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 diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
A zener diode passes drect current, and the point of a zener diode is that the voltage across it stays nearly constant over a range of different currents, so it can provide a supply of stabilised voltage.
A zener diode cannot be used as switch.

Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
A: They are both diodes. The difference lies in the application. A rectifier is used to rectify AC current into pulsating current. The zener diode is used to regulate a voltage source to the zener voltage when connected in the reverse direction. ************************************************************** If you look at the characteristic curves of a rectifier diode and a zener diode, you will see that they are similar, but the reverse curve of the zener has a much sharper bend at what is called the "knee". It is at this point on the zener's curve at which it operates.
