This article sets out to discuss the 9401120000 application field and working principle for TVS (Transient Voltage Suppressors), Varistors, and MOVs (Metal Oxide Varistors). Transient Voltage Suppressors, also known as TVS for short, are surge protection devices designed to respond immediately to transient voltages on a power line. These voltage spikes are typically caused by extreme loads or inductive loads and can create significant power fluctuations. TVS devices function mainly by absorbing the energy of the surge and by clamping the voltage to a more manageable level. The TVS part commonly used is the 9401120000, a low capacitance varistor that provides up to 170 volts protection on the positive and negative lines. The working principle of a TVS device is simple- when the voltage reaches a specific level, an influx of charge flows through it. This influx causes the device to be activated, which then clamps the voltage to a certain level. This process can be illustrated below. When the voltage reaches a given threshold, the flux of charge is transferred from point A to point B, creating a new power curve. As the new power curve is more stable, the voltage of the circuit is clamped at a certain level. This is a basic example of how the TVS 9401120000 protect the circuit from voltage peaks. Varistor, on the other hand, is a type of surge protection device that operates by absorbing energy. They are designed to react quickly to transient changes in voltage and current, providing a more stable power source for electronic systems. The working principle of a Varistor is based on a simple zinc oxide material. When exposed to higher current levels, this material starts to produce electrons which create a “reserve” of power. When the current flow drops below a certain level, the reserve power is discharged, stabilizing the circuit. Varistors can be used in a variety of applications, including over-voltage protection for power supplies, motor control circuits, and high frequency filtering. The 9401120000 is an example of a varistor that has low capacitance and provides up to 170 volts protection across the positive and negative lines.A MOV (Metal Oxide Varistor) is a type of surge protection device that utilizes a metal oxide material. This material behaves differently than the zinc oxide material used in varistors, allowing it to respond to changes in voltage more quickly and efficiently. The metal oxide material is also more resistant to heat, allowing MOVs to provide greater protection against voltage and current surges. The working principle of the MOV is similar to that of a varistor, in that it absorbs energy when current levels are high and releases it when current levels drop. The metal oxide material used in an MOV allows it to react quicker than other surge protection devices, providing additional safety against surges and spikes. The 9401120000 is an example of an MOV, offering up to 170 volts protection on the positive and negative lines.In conclusion, TVS (Transient Voltage Suppressors), Varistors, and MOVs (Metal Oxide Varistors) all serve a similar purpose: to provide protection against voltage and current surges. The 9401120000 is a particularly useful device, providing up to 170 volts protection on the positive and negative lines. The working principle of these devices is based on simple materials, and they are designed to react quickly to changes in voltage and current levels in order to protect sensitive electronics from damage.
