In my understanding a varistor would be used within an electronics circuit to protect against voltage spikes. Zener barriers are used to limit the potential power available to a remotely located instrument device which are located in hazardous areas to prevent enough energy to cause a spark which could result in an explosion.
Thank you
Can you please tell us how klystrons work?
Good video....Why any other switching device like other transistors can't be used?
Thanks.
Good point, as far as I am aware there would be no reason that a transistor with reverse bias could not be used in place of the zenner diode
In which case would you choose a zener barrier above a thermally protected varistor?
