TVS devices are widely used in electrical systems for protecting them from overvoltage transients and for providing signaling functions. ROV05-621K-2 is one of the TVS devices, which is used to protect MV and LV electrical systems for home appliance and transportation applications. It is a high-performance transient voltage suppressor that is suitable for a variety of applications, including surge suppression, ESD protection, and EMI/RFI filtering.

ROV05-621K-2 is a low-profile, dual MOV (metal oxide varistor) transient voltage surge suppressor (TVSS) device. This device is designed to protect sensitive electronics from voltage transients induced by lightning, power cross, and switching transients. It features a robust industry-standard dual MOV design that can withstand up to 2kA (8/20 μs) of surge current. This device is available in a wide range of voltage grades, from 6.4V to 25V, with an operating temperature range of -40°C to +85°C. It is also certified to UL, cUL, VDE, and IEC standards.

ROV05-621K-2\'s working principle is based on the principle of the MOV. It is a two-element, nonlinear resistor with a nonlinear voltage-current characteristic. The two elements, one active and one passive, form a voltage-dependent series resistance in parallel with a reverse-biased diode when an external voltage is applied. When the voltage across the MOV exceeds its rated voltage, a large current is created, and the MOV begins to conduct, protecting the electronic circuitry from the surge.

In addition to the MOV, ROV05-621K-2 also features a capacitor for EMI/RFI filtering. The capacitor is designed to reduce the amount of high-frequency electromagnetic interference that can cause problems in the circuit. The MOV and capacitor are connected in parallel to form a low-pass filter, which helps reduce the amount of noise generated by the system.

ROV05-621K-2 can be used in a variety of applications, including industrial, automotive, and consumer electronics. In automotive applications, this device can be used to protect onboard electronics from power surges. In industrial applications, it can be used to protect equipment from lightning and power transients. In consumer electronics, it can be used to protect sensitive devices from power transients.
