AVR101A3R3FTA is a transient voltage suppressor which belongs to the family of TVS(Transient Voltage Suppressors). TVS are protective components designed to protect electronics from unwanted high voltage spikes which can cause severe damage to the underlying circuitry in a device. The AVR101A3R3FTA is a metal oxide varistor (MOV) with a working voltage of 3.3V and a peak pulse voltage rating of 10V.

MOVs are used to protect against surges, spikes, high voltage transients, electrostatic discharges, and other high energy events which may pose a threat to electronics. They are designed to absorb and dissipate large amounts of energy in a short time, protecting the circuitry from the full brunt of the incident. MOVs consists of a metal oxide layer, often between two surface electrodes. When a voltage spike is detected, the metal oxide layer will quickly dissipate the energy of the voltage spike, thus preventing damage to the underlying circuitry.

AVR101A3R3FTA is suitable for a number applications including, but not limited to; personal computers, game consoles, stereos, televisions, and home automation. It can be used to protect against voltage spikes that occur instantaneously, such as from lightning, power outages, or from the introduction of other incompatible equipment. It can also be used to protect against smaller voltage spikes that occur over a longer duration of time, such as those generated by power cycling, brownouts, or induction.

When connected in parallel to the circuit, the voltage will be regulated to the rated voltage of the MOV. This is achieved by the MOV drawing any current that rises above the rated voltage and dispelling the resonant energy through a large internal resistance. This large internal resistance allows only a small current to pass through, thus greatly limiting the amount of power that can reach the circuit itself.

In summary, the AVR101A3R3FTA is a MOV transient voltage suppressor, designed to absorb high voltage spikes and dissipate them as heat. This will protect the underlying circuitry in a device from damage and degradation due to the high energy. It is suitable for a wide range of applications and will protect against instantaneous voltage spikes as well as smaller voltage spikes caused by power cycling, brownouts, induction, and other events.
