Varistors, or voltage dependent resistors (VDRs), are electrical components that contain metal oxide compounds, typically zinc oxide, which results in an electrical behavior known as the nonlinear resistance i.e. they can be adjusted by controlling the applied voltage. When there is a voltage surge, the varistor can decrease its resistance and limit the peak surge voltage to a safe level. The varistor\'s resistance can be adjusted very quickly and accurately, enabling it to effectively protect circuits against high voltage transients.

The V575LA10PX2855 is the NXP\'s newest varistor specifically optimized for signal line protection and communication line protection. It is a medium power device with an adjustable load current of 5A. The device has an operating voltage range of 5V-75V, and its peak surge current rating is 2855A (10/1000 μs). Its maximum peak pulse power rating is 1820J, and the maximum leakage current is 50mA. The V575LA10PX2855 has a lightning surge threshold of 6V.

The V575LA10PX2855 is well-suited for protection applications involving high voltage, capacitively loaded lines. It can be used in automotive and industrial applications such as engine control units, actuators, electronic control units, digital signal processors, and power inverters. The device can also be used to reduce electrostatic discharges and provide over-voltage protection, making it especially suitable for communication systems and other digital circuits.

The working principle of the V575LA10PX2855 is relatively simple, but highly effective. When the voltage surge exceeds the device\'s threshold, the zinc oxide is compacted and electrical current is diverted to the varistor. This redirects the surge current around the protected circuit and reduces the voltage to a safe level. This limits the amount of energy that is released, and thus p
