TVS or transient voltage suppression devices provide overvoltage protection for a wide variety of electronic components and systems. The VDRS20W140BSE is one such device, specifically designed for strong EMI suppression. It is a two-terminal Varistor/MOV (Metal Oxide Varistor/MOV) device designed to provide overvoltage protection for sensitive analog, digital, and power supply signals. This device has a very low clamping voltage and fast response times.

The application area for this device varies from low voltage power supplies to automotive electronics systems, and it is particularly suitable foruse in industrial applications and high-frequency power transmission systems. The VDRS20W140BSE is a popular choice for its robustness and ease of use, and is ideal for applications requiring low fuse trigger levels and fast response times.

The working principle of the VDRS20W140BSE is based on a two-terminal varistor/MOV. When a voltage above the trip point of the device is applied across its terminals, the MOV begins to conduct, clamping the applied voltage and preventing its rise beyond the trip point. The device’s internal structure ensures that the time of response remains very low, making it suitable for use in critical situations where even a slight difference in timing could mean a malfunctioning system.

The structure of the VDRS20W140BSE consists of two very thin layers of metal electrodes placed over one another. These layers are separated by a thin insulating layer. When a voltage is applied to the device, the voltage causes the layers of metal to moveBy, allowing current to flow. This generates a strong electrostatic field, which clamps any voltage provided to the device and prevents its rise beyond the trip point. This structure also ensures very fast response times.

The VDRS20W140BSE is highly durable and reliable, allowing it to be used in a variety of harsh environments. It is resistant to thermal shock, UV radiation, and other environmental factors, making it suitable for outdoor use. It also features a very low trigger voltage and a wide operating temperature range, making it a versatile device for use in a variety of applications.

In addition to its protective properties, the VDRS20W140BSE also provides strong EMI suppression. Its low clamping voltage and fast response times make it suitable for systems that demand effective protection from EMI, such as power line communication and power line networking systems. Its robust construction and wide temperature range make it reliable for use in industrial environments.

Overall, the VDRS20W140BSE provides strong protection for sensitive analog, digital, and power supply signals. Its robust construction and wide temperature range make it suitable for use in harsh environments, and its low clamping voltage and fast response times make it ideal for use in applications prone to EMI. The device’s two-terminal varistor/MOV structure ensures reliable protection and quick response times, making it a versatile and reliable choice for protection against overvoltage.
