ROV05-301K-S-2 is a type of TVS - Varistors, MOVs (Transient Voltage Suppressors) device. It offers superior protection against transient overvoltage surges, esential in applications where voltage spikes commonly occur. ROV05-301K-S-2 is effective in protecting circuits against voltage disturbances generated internally by the application or externally by other components.

ROV05-301K-S-2 is a multi-layered varistor that is designed with high power dissipation capabilities. It typically has three layers of ceramic material -- a main body, a capacitor core, and an inner core, all connected in series. The outer core and inner core act as electrodes which act as a protector from transient overvoltages.

The main metal oxide layer between the two electrodes absorbs the excess voltage, essentially acting as a voltage regulator. This layer dissipates energy and so it reduces the voltage and current that reaches the protected circuit. The main body and capacitor core layer are composed of zinc oxide material.

ROV05-301K-S-2 is a general-purpose overvoltage protection device and is ideal for use in sensitive industrial, automotive, and consumer electronic applications. It is also suitable for protection against transient voltages in data communication systems, fiber optical cables, audio and video systems, LED systems, power supplies and solenoid valves. ROV05-301K-S-2 is suitable for broadband applications and is also excellent for low voltage protection.

The working principle of ROV05-301K-S-2 is quite simple. When a voltage exceeding a predetermined limit is applied to it, the voltage difference between the oxide layer and the cathode is lower than the breakdown voltage. This causes electrons to move from the base of the circle to the gap between the layers, thereby forming a conductive path.

The device then operates in its bidirectional mode, where current can flow through it both ways. This in turn produces a short-circuit current, diverting some of the current away from the protected circuit. As the voltage source connected to the protected circuit reduces in magnitude, the operating point is then returned to its normal non-conductive state.

ROV05-301K-S-2 can be applied in both AC and DC circuits and it is designed to withstand 330V AC voltage or 450V DC. The operating temperature range for this device varies from -25°C to +85°C. It offers excellent transient protection performance with fast response time, offering surge ratings of up to 4.5kV.

ROV05-301K-S-2 is an effective and reliable overvoltage protection device. It offers robust, effective, and reliable protection against transient voltage surges and is a cost-effective solution for protecting sensitive circuits against voltage irregularities.
