Hi

Does anyone know how to calculate the noise from a Zener diode?

Ultimately I want to know this because I want to calculate the SNR of a circuit containing a Zener diode.

I have been looking into Thermal noise theory. I was looking at something like T=(Power/Bandwith)/Kb

Kb: Boltzmann constant 1.381 x 10^-23

Power: 300 [mW]

Bandwith: 24 [Khz]

But this results in an unreasonable number.

By the way.. its a typically standard zener BZX84C5V1.

Am I on the right path? Please comment if you have some thoughts.
