TVS – Varistors, MOVs – are extremely important parts in modern power electronics. A TVS in particular links two worlds, the world of power electronics and the world of temperature control. On one hand, a TVS is designed to provide a high level of protection from voltage spikes and provide voltage control while on the other hand, it is designed to protect sensitive components from high temperatures. ROV14H751K-2 is a standard type of TVS which combines these two important features.

An ROV14H751K-2 is a surface mount type of TVS which is designed for power semiconductor applications like AC/DC converters, DC/DC converters, power inverters, motor controllers etc. The shut down voltage of the device is 14V and the rated stand-off voltage is 7.5V. This type of TVS is perfect for suppressing high voltage surges and spikes in power electronic applications, and can handle up to 1.3kA surges with a maximum peak pulse power rating of 411W.

In terms of design, the ROV14H751K-2 has a thermal shutdown temperature of 155°C and a maximum junction temperature of 175°C. Its capacitance is between 11-16pF depending on the voltage applied. The assemblies are highly configurable with a range of available sizes from 2.0mm to 8,5mm as well as different terminal technologies including QuickFit and SMT (Surface Mount Technology). This type of device is made up of two parts: the Varistor and the diode.

The Varistor is the main component of the assembly and is designed for voltage and surge protection. It is a non-linear device which means that its resistance varies with changes in voltage. In the steady state, the Varistor is basically an open circuit so it has a high resistance. However, if a sudden high voltage spike is applied, it will convert this energy into heat which reduces the overall peak voltage and current. In other words, it can absorb a large amount of energy and dissipate it in a short amount of time, making it ideal for over-voltage protection.

The diode is the second component of the device and is important for protecting sensitive components from heat. The diode is used to block reverse energy flow, which helps to keep temperatures low and protect vulnerable components from overheating. This is critical to ensure the safety of the system and provide a longer product life cycle.

ROV14H751K-2 is an indispensable component in power electronic applications. It is reliable and offers a high level of protection from voltage surges, and its thermal shutdown temperature prevents components from overheating. Its dual design, with both a Varistor and a diode component, makes it a highly effective and efficient device for protecting sensitive components, and its configurable size and terminal technology further add to its appeal.
