ROV10-271K-S-2, also known as a transient voltage surge suppressor (TVS), is a type of protection device used to protect electric circuits from damage caused by high voltage transients. TVS devices are commonly used in power conversion circuits, automotive applications, and other applications where transients or spikes in power or voltage are a concern. The ROV10- 271K-S-2, in particular, is capable of providing superior protection against transients and voltage spikes across a wide range of environments and applications.

The ROV10-271K-S-2 is a varistor-type device that provides protection against transients in the range of 2V to 150V peak (with respect to ground) at 10ns to 10ms (10µA to 10 mA). The device can also provide a reduced voltage spike of up to 75V peak for short-duration transients. The device’s ultra-low capacitance and high-level peak protection make it particularly effective in suppressing high amplitude transients with very short pulse duration, allowing it to effectively perform its active clamp duty cycle.

The ROV10-271K-S-2 is typically constructed using a ceramic disk with copper-backed electrodes. A thin film of varistor material is bonded to the electrodes and then overcoated with a protective coating. Its low capacitance characteristics help to reduce switching noise and eliminate high frequency ringing, making it an ideal choice for low-noise circuit designs. In addition, the device is also configured to provide an enhanced EMC (electromagnetic compatibility) level that exceeds the IEC and UL standards.

The device provides superior ESD protection, and its high surge current capability makes it ideal for automotive and other harsh environment applications. The device is also resistant to temperature cycling, and is capable of withstanding up to 2C°C of altitude and humidity changes without experiencing any loss of performance. Additionally, the device is RoHS compliant, with lead-free construction.

When operating, the ROV10-271K-S-2 works by sensing high-voltage transients and clamping their magnitude to safe voltage values. The device achieves this by redistributing the energy of the transient across its components, meaning that the energy is dissipated as heat instead of potentially causing damage to the surrounding circuitry. The device is rated to absorb up to 200W of power, typically dissipating 5-10W while doing so.

In summary, the ROV10-271K-S-2 is a robust, reliable varistor-type transient voltage surge suppressor that provides superior protection against transients and voltage spikes across a wide range of applications. Its low capacitance, high-level peak protection, EMC compliance, high surge current capability, and other features make it ideal for use in power conversion, automotive, and other applications where transients or spikes in power or voltage are a concern.
