VC0805K121R020 Circuit Protection

The VC0805K121R020 is a high voltage AC transient suppression device. It offers a light and compact solution for lightning protection, surge protection, and other high-voltage AC applications. This surge absorber has a wide operating voltage range, allowing it to provide effective protection even when operating voltages increase or decrease rapidly. It is also highly resistant to moisture, allowing it to perform reliably in wet environments.

The VC0805K121R020 is classified as a TVS (Transient Voltage Suppressor) or MOV (Metal Oxide Varistor). These are used for protection from overvoltage, overcurrent and short circuit conditions. This surge absorber operates on the principle of a voltage-dependent resistor. It is made up of a metallic oxide material, which has a highly non-linear resistance characteristic. When the applied voltage exceeds a certain threshold, the resistance of the MOV increases rapidly, and the current is diverted to ground and dissipated as heat.

The VC0805K121R020 has a wide operating voltage range, making it suitable for a variety of different applications. It is typically used for surge protection, lightning protection, and other high-voltage AC applications such as power supplies and industrial control systems. It also has an impressive lightning surge protection capability, with a rating of Ipp: 8/20 µs – 80KA (positive), 8/20 µs – 90KA (negative). This ensures excellent protection from lightning surges and other transient voltages.

In summary, the VC0805K121R020 is a high voltage AC transient suppression device that offers a light and compact solution for lightning protection, surge protection, and other high-voltage AC applications. It is classified as a TVS or MOV, and operates on the principle of a voltage-dependent resistor. It has a wide operating voltage range and an impressive lightning surge protection rating, making it ideal for use in a variety of applications.
