TVS (transient voltage suppressors), MOVs (metal oxide varistors) and V47ZA7P are three very different components belonging to the same group of electrical components. TVS and MOVs both function as surge suppressors, while V47ZA7P is a Differential Mode (DM) interference filter.

TVS components are designed to protect sensitive electronic components from voltage transients caused by lightning, electrostatic discharge, or any other form of electrical overstress. They are made up of solid-state components which are typically connected in series with the protected component. The TVS component will absorb the transient voltage while also providing a path to ground for any current flowing through the circuit. However, it should be noted that the TVS component can become saturated if exposed to a large enough surge, rendering it ineffective.

MOVs are similar to TVS components but they are designed to protect against overvoltage fluctuations rather than voltage transients. Unlike TVS components, MOVs are not solid-state components and instead are made up of metal-oxide materials. These materials allow the MOV to absorb the energy associated with the overvoltage, diverting it away from the electronic components it is connected to.

V47ZA7P is a Differential Mode (DM) interference filter. Differential Mode interference is when an electrical signal coming from one source couples into an adjacent wire and creates a noise on it. In the V47ZA7P, the positive and negative lines are isolated from each other with an RF attenuator and a common-mode filter, which filters out the noise on the line. This reduces the noise on the system and increases the system\'s signal to noise ratio.

In conclusion, although TVS, MOVs and V47ZA7P are all components belonging to the same group of electrical components, they each serve very different purposes. TVS are made to protect against voltage transients, MOVs protect against overvoltage fluctuations, and V47ZA7P is a DM interference filter designed to reduce noise on the line.
