TVS (Transient Voltage Suppressor) devices like Varistors, MOVs (Metal Oxide Varistors), and SCRs (Silicon Controlled Rectifiers) are electronic components used to protect circuits from electrical transients (fast, momentary overvoltage). VDRS05C460TSE is a series of varistors produced by Eaton and offers excellent protection against high-energy transients in a wide range of applications.

VDRS05C460TSE varistors are non-linear, multi-layered metal oxide overvoltage protective devices (MLVs) designed for circuit protection for a wide range of applications. They\'re typically used in telecommunications, lightning protection, next-generation industrial controllers, power supplies, renewable energy systems, medical and aerospace applications.

VDRS05C460TSE’s working principle is based on the fact that as applied voltage exceeds a specific breakover voltage threshold, the varistor will break down, resulting in a non-linear current-voltage (I-V) curve. This process allows excess current to be diverted away from the protected components and routed back to the source, resulting in protection from transients and high-frequency orders of magnitude surge levels.

In addition to its protection capability, this varistor also includes a high-frequency filtering effect, due to its smaller equivalent series resistance (ESR). This allows it to absorb higher frequency interference, providing clean power to the connected device or system. It also offers a low clamping voltage, so system components can be readily protected against fast transients occurring on the connected power-rail.

VDRS05C460TSE varistors are designed to protect against transients up to 1500W peak power and 30V DC breakdown voltage with an operating temperature range between -55°C and +125°C. It has a maximum peak current rating of 18A in a broad temperature range of -55°C to +125°C, allowing it to operate reliably and efficiently in a wide range of high-temperature applications.

The flame retardant version of the VDRS05C460TSE is available for applications that require a high level of fire protection. This varistor has a self-extinguishing rating of UL94V-O, making it perfect for sensitive applications such as medical devices, motor controllers, and other applications that require high levels of fire protection.

Finally, the VDRS05C460TSE is packaged in a small (5x4mm) surface-mount form factor that is designed to save board space, making it ideal for small electronic systems such as consumer electronics and IoT applications.

In summation, the VDRS05C460TSE varistor series offers an excellent, cost-effective solution for a wide range of applications that require protection from both high and low energy transients. It provides low clamping voltage, a high-frequency filtering effect, and a high peak power rating, making it the ideal choice for high-temperature applications such as telecommunications and medical systems. Its small form factor and excellent flame retardant rating make it well suited for sensitive applications such as consumer electronics.
