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.

What type of diode maintains constant current?
zener diode
Where from to get ratings and specifications of zener diode?
There are thousands of different zener diode types...use the internet to locate a data sheet for a particular type.
How do you xxplain the zener shunt regulator?
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
What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
What type of diode maintains constant current?
zener diode
What is the difference between an ideal zener diode and practical zener diode?
Zener diode is heavily doped pn junction diode.
Where from to get ratings and specifications of zener diode?
There are thousands of different zener diode types...use the internet to locate a data sheet for a particular type.
How replace branches of diode with zener 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.
How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
What type of current is used in zener diode?
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.
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.

Who invented the zener diode?
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
What is the difference between rectifier diode and 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.
What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
