Effects of Temperature on Zener Voltage

[@asifhasanrizvi4230]

As we know that Zener breakdown voltage should decrease on increasing temperature, but in the above question, this is not following. That's because there is a range of Zener potential defined for which temperature coefficient is positive or negative. For Zener diode having Zener potential less than 6 Volt, have negative temperature coefficient i.e. on increasing temperature, final zener potential will decrease. And if the Zener potential is greater than 6 Volt, then it have positive temperature coefficient as Avalanche breakdown will be predominant. In above question, Zener potential given is 10 Volt which is greater than 6 Volt. That's why the final Zener potential is greater than 10 volt.

Thank you bro.I had this doubt in mind and i cound not find an answer for it.Finally it's u who clarified that...

[@YZ-rn6bl]

yes the final answer should be 10 - 0.54

[@uzumakiluffyjeager8615]

Did you become hokage atlast

[@jorgerive7335]

@@YZ-rn6bl no....since the Vz=10, it has a positive tempco...so as temperature increases, so does the zener voltage. if the Vz were less than 5 or 6, then the tempco would be negative, and Vz would decrease with increasing temperature.

thankyou for the playlist Sir!!!

[@jancydas5569]

As the temperature increases, zener breakdown voltage decreases.. zener breakdown is negative temperature coefficient

[@YZ-rn6bl]

Correct!

Sir please make the video on hall effect and there numerical.

upload opamp plz

[@sivapriya1533]

Room temperature is 25 or 27 deg celcius? Which one correct?

[@Vernacularpressact]

27

I love you so much sir

[@vedanshrai2169]

Please add notes or PPT as study material

[@Prashantsingh896]

Zener breakdown have negative temperature coefficient, but in the example in this video you have taken positive. Why so ?

[@shubhamnayak9369]

Prashant singh as far as I know when you increase the temperature whole VI characteristics shifts to left. Therefore forward bias voltage decreases but reverse bias voltage increases.

[@Zakirkhan-nv3xw]

Temperature coefficient can be positive or negative for Zener Diode. A positive TC means that the zener voltage increases with an increase in temperature or decreases with a decrease in temperature. A negative TC means that the zener voltage decreases with an increase in temperature or increases with a decrease in temperature.

delta vz is comming 0.18 i think sir has calculated wrong
