All semiconductor are sensitive to temperature. Some vary greatly some not so great. Zeners are not one of class as greatly. Zeners do change voltage slightly as temperature vary like all active devices. But to use one as a temperature sensor is bad idea.

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 are application of zener diode?
Applications of Zener diode: a.)It Regulators. b.)It Controlled Comparators. c.)It Limiters. d.)It is Part in Power Supplies.
For zener diode the temperature coefficient is?
positve
When current through a zener diode increases by a factor of 2 by what factor does the voltage across the zener diode increase?
If the zener diode is in zener breakdown the voltage across the zener diode remains constant regardless of current (for the ideal zener diode). Real zener diodes have parasitic resistance that causes the voltage across the zener diode to increase slightly with increased current, but due to temperature dependant variations in this parasitic resistance as well as temperature dependant variations in the zener breakdown voltage, this change in voltage in real zener diodes cannot be described by a simple linear factor.
What type tempcoefficient does the zener diode have?
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 is the difference between an ideal zener diode and practical zener diode?
Zener diode is heavily doped pn junction diode.
What are different applications of the diode?
Different applications of diode include:Rectification of voltageswitching circuitsclamping applicationsvoltage reference (zener Diode)phase lock loop/FFLinfrared applicationssignal amplifierssensorshigh frequency micro-wave oscillators.
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
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 function of zener?
zener diode is a revers bias diode which used for voltage regulation.
What is the leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
