    Default Difference between TVS Diode and MOV?

    What are the physical, electrical, performance, and price difference between an MOV and TVS diode in the transient filter stage of a power supply?
    From what I read, they’re both used to reduce voltage spikes coming from the input.

    MOV's cost less, can handle much more energy, but they age quicker. Another downside is that they allow for higher voltages than transils (or TVS).

    There is another enhanced version of the MOV, called Zinc oxide varistor which seems to be much better in some areas, however still the clamping ratio is not so good compared to TVS.
