TVS (Transient Voltage Suppressor) devices are designed to protect sensitive electronic components from destructive electromechanical discharges. Varistors, MOVs (Metal Oxide Varistors) and TVS diode arrays are the three most commonly used forms of transient voltage suppression (TVS). The ROV20H821K-S (Solid-State Transient Voltage Suppressor, 3-Pin) is a part of the TVS diode family and is specifically designed for high-powered, high-voltage application fields.

The ROV20H821K-S is a versatile, robust, and reliable TVS device for superior protection of electrical or electronic components from destructive discharges of transient voltage. It is rated for up to 1500W continuous power dissipation with a maximum clamping voltage of 800V, and is capable of clamping and absorption of energy levels up to 4kW. Furthermore, it is designed for surface mounting, allowing it to fit tight spaces that require it in electrical and electronic equipment. Its design and superior features make it suitable for a wide variety of application fields.

The application fields of the ROV20H821K-S include, but are not limited to, the automotive industry, industrial and consumer applications, the aerospace and medical industries, networking and communications devices, and communications and lighting systems. In each of these applications, the ROV20H821K-S provides dependable surge protection for those devices subject to voltage transients. This ensures that the sensitive components in those devices are not damaged or destroyed, and that they can continue to operate reliably.

In order to protect these components, the ROV20H821K-S relies on its metal oxide varistor (MOV) construction. MOV technology consists of a semi-conductor device in which two or more plates are connected either in series or in parallel. When a transient voltage spike occurs, the oxide-based material in the device will conduct away from the plates, clamping the voltage and keeping it within safe limits for the device. This ensures that the sensitive components in the device can be protected from the spiked voltage.

The ROV20H821K-S is also designed with a high current rating – up to 800A – for start-up or fault conditions, as well as an operating temperature range of -55°C–125°C. It also has a high surge current rating of 10kA. This allows it to withstand both short and long duration transients, yielding a high degree of component protection when used in electrical and electronic systems.

In conclusion, the ROV20H821K-S was created as a dependable and cost-effective solution for protecting sensitive electrical and electronic components against transient voltage. Its metal oxide varistor (MOV) construction provides reliable protection against transient voltages, while its operating temperature range and high current rating make it suitable for a myriad of application fields. Furthermore, its compact design and robust construction allows it to fit tight spaces, making it an ideal choice for use in high-powered, high-voltage application fields.
