AMCV-0805-5R5-C180N-T Circuit Protection

AMCV-0805-5R5-C180N-T is a type of Transient Voltage Suppressor (TVS) device. It is also referred to as a Metal-Oxide-Varistor (MOV). This device is used to protect vulnerable electronic components from over-voltage transients or other high-voltage events. As with other TVS devices, this device works by quickly diverting the energy from the transient voltage away from the protected component or circuit, preventing damage to the component.

Although designed for use in devices where extremely fast transients are present, AMCV-0805-5R5-C180N-T can also be used in applications where lower frequency surges are present. This product from AMC is particularly well-suited for applications that require high clamping voltage, small size, and high reliability.

The working principle of MOVs like this one is based on the electrical behavior of the metal-oxide material used in its construction. The metal-oxide material acts like a variable resistor, in that its resistance changes with the amount of voltage applied to it. When a voltage higher than the rated breakdown voltage is applied across the device, the resistance of the metal-oxide material quickly decreases. This allows a large amount of current to flow through the device, diverting the surge energy away from the component it is protecting. As the surge dissipates, the resistance of the metal-oxide material increases, thus limiting the current flowing through the device.

The AMCV-0805-5R5-C180N-T device has a Breakdown Voltage (V BR ) rating of 5V and a Clamping Voltage (V C ) rating of 180V. This device is rated for a maximum power dissipation of 400W, a maximum peak surge power of 3,000W, and a maximum peak current of 175A. This device is available in an 0805 package, in which the body is 8x5mm with a 5.5mm height.

In summary, the AMCV-0805-5R5-C180N-T is a type of MOV that is used to protect electronic components from over-voltage transients. Its working principle is based on the electrical behavior of the metal-oxide material used in its construction. This particular device is rated for a V BR of 5V, a V C of 180V, a maximum power dissipation of 400W, a maximum peak surge power of 3,000W, and a maximum peak current of 175A.
