TVS (Transient Voltage Suppressors) is a type of device that is designed to protect sensitive electronic equipment from high-voltage transients. The main aim of these devices is to clamp the transient voltages, absorb the energy from the voltage spike and then ‘shunt’ it away from the sensitive device. This type of device is often referred to as a TVS diode. Alternatively, you might have heard of MOVs (Metal Oxide Varistors) or Varistors which are, essentially, similar devices that provide protection from transient voltages.

ROV07H201K-S is a MOV (Metal Oxide Varistor) manufactured by Littelfuse. It is designed to protect electrical and electronic systems from overvoltage transients and fuses which occur in both AC and DC systems. The move is rated at 200V and has a holding current of 2A, giving it a maximum power rating of 400 Watts. The duty cycle of this MOV is 40A/1000sec and its maximum surge current rating is 18A.

The ROV07H201K-S is typically used in a wide range of applications such as computers, appliances, networking switches, ac/dc converters, motors and automotive applications. These are just some of the common applications of this MOV and it can be deployed in almost any system that needs to be protected from high voltage transients.

The working principle of the ROV07H201K-S is simple but effective. The MOV operates by ‘clamping’ the overvoltage transients when they occur, therefore ‘shunting’ them away from the sensitive components. During normal operation, the MOV has a high resistance which prevents the flow of current, however, when the voltage rises above its rated voltage, the MOV quickly becomes a low-impedance path and diverts the excess current elsewhere. This prevents the voltage spike from damaging the system components.

When the MOV has done its job of protecting the system, it reverts back to its original high resistance state. This means that it can be used multiple times, ensuring that the system is continuously protected. It also means that the MOV must have low leakage current and thermal runaway so that it does not damage the system.

Overall, the ROV07H201K-S is a reliable and robust solution for protecting electrical and electronic systems from overvoltage transients and fuses. Its simple working principle, coupled with its low leakage current and thermal runaway, makes it an ideal choice for protecting a variety of different applications from high voltage transients. The ROV07H201K-S is an ideal device for those who require an efficient and effective protection solution.
