TVSs (Transient Voltage Suppressors) such as Varistors, MOVs (Metal Oxide Varistors) and diodes are semiconductor devices that can quickly restore the equilibrium of a system disrupted by a voltage spike or transient. ROV20-330M-S is one of the most widely used TVSs, and it has been widely used in various kinds of electronic device applications and electrical systems. Below will discuss the application field and working principle of the ROV20-330M-S.

Application Field
ROV20-330M-S is a ceramic based TVS that provides transient surge protection for a wide range of commonly used power systems. It is suitable for protecting electronic devices such as computers, TVs, electronic products, motors, and switches. It can also be used in critical applications such as automotive, industrial, LED lighting, photovoltaic, power grids, and telecommunications to protect against voltage and current surges.

ROV20-330M-S can be found inside products like smartphones, computers, and internet routers as surge protection devices. It features a variety of common and innovative options, such as solid state or thyristor switching, wide operating temperature range -55°C to +125°C, low temperature co-efficient leakage current, low capacitance, high power dissipation capability, and fast response time. Its surge capability is up to 400A (10x1000µs).

Working Principle
When there is a voltage surge, the ROV20-330M-S absorbs the excessive voltage, dissipates it, and quickly restores the equilibrium of the system. The working principle of the ROV20-330M-S can be simplified as follows. When there is an excessive voltage, the ceramic layer of the ROV20-330M-S will become disabled and the MOV (Metal Oxide Varistor) will start to divert the excessive voltage as well as dissipate it. During the process, the excessive current will flow from the ceramic layer to MOV, and then it will be diverted to the ground. When the voltage reaches its normal level, the MOV will be re-enabled, and the ceramic layer will be functioning again. This will eventually restore the normal voltage in the system.

ROV20-330M-S is a reliable and highly efficient TVS that provides transient surge protection for a wide range of commonly used power systems. Its excellent performance and features make it a preferred choice among many applied industries. It is also capable of withstanding voltage and current surges up to 400A (10x1000µs), providing superior protection for electronic products and electrical systems.
