Transient Voltage Suppressors (TVSs) are specialised, solid-state components used to protect other components and circuits from voltage transients or electrostatic discharges. Traditionally, TVSs took the form of sacrificial Zener diodes but, whilst still widely used, they cannot meet all requirements. Metal Oxide Varistors (MOVs) were developed and are now widely used in the protection of circuits, components and application such as line-voltage (L-N, L-PE, N-PE, LINE-LINE or LINE-NEUTRAL) protection. They are designed to absorb and dissipate large transient voltages and currents to a level considered safe by the circuit.

ROV14H511K-S is a surface mount TVS-Varistors, MOVs component. It comes in a 1205 (0805 inch) SMD (Surface Mounted Device) package and features excellent thermal stability, high surge handling capability and low capacitance. It is ideal for applications such as electrical noise suppression, load switch protection or peak power dissipation components.

The TVS-Varistor, MOVs provides a multi-level response to voltage transient events; when exposed to an overvoltage event, the junction will open and draw current. This current passes through a snap-back circuit formed by the resistor in series with the varistor, allowing the voltage of the transient to be clamped to the desired breakdown voltage. The device also features a wide and symmetrical breakover voltage level versus junction temperature characterization which simplifies circuit design and facilitates stable operation of the protective circuit.

The TVS-Varistors, MOVs provides protection in several ways including transient event absorption and short-circuit protection. It provides protection against ESD such as charged device model (CDM) and human body model (HBM). It also provides return-to-zero (RZ) protection for systems running on high-speed or high-power serial data buses.

ROV14H511K-S also offers superior thermal stability and low capacitance, making it ideal for high-speed circuit applications in which lower power dissipation is desired. The device also offers low leakage current compared to traditional MOV devices, allowing for improved impedance in the circuit at high frequencies. The low capacitance also improves EMI performance, allowing for reliable protection of data lines and other sensitive components.

In summary, ROV14H511K-S is an ideal TVS-Varistors, MOVs device for protection in applications such as circuit protection, load switch protection, ESD suppression, data lines, and protection against overvoltage events. The device is capable of providing fast, efficient, and reliable protection of critical components and systems.
