V480LC80CPX10 is a highly reliable and surgeproof protection device used mainly for transient suppression applications offered in a low-profile SMD package by NXP Semiconductor. Also known as a Zinc Oxide Varistor, this varistor is primarily designed for ESD, EFT, surges and lightning protection against over-voltage conditions present in automotive, industrial, consumer and medical applications.

The V480LC80CPX10 is designed to meet the Automotive Electronics Council AEC-Q200 standard for circuit protection components used in the automotive industry. It works within voltage ratings of 20 VDC to 1000 VDC, continuous operating voltage ratings of up to 300 VDC, and a rated energy of 2600J with an 8V/20uS design. The varistor also has an impressive rated current of 40A and a capacitance of 30pF at 1KHz. It is highly resistant to surge currents, over-voltage, and extreme environmental conditions thanks to its low resistance and excellent reliability.

The working principle behind V480LC80CPX10 is the same as any other varistor. It works on a proven mechanism where special metal-oxide semiconductors are used to regulate the current flow in electronic circuits and protect them against power surges. The metal-oxide layers have a carefully-controlled thickness of around microns and consists of zinc oxide as the main component. These layers conduct electricity when there is a low voltage (up to a certain level) but become heavily resistive at higher voltages.

The operation of the varistor occurs when it is subjected to a high voltage pulse. As the voltage increases, the resistance of the materials decreases, and current starts flowing. The voltage-dependent current flows in the direction of the external circuit, limiting the rate of rise of the voltage. Thus, there is no further increase in voltage and the current is quickly diverted away from the circuitry. As the quickly flowing current reaches the maximum possible, the voltage starts decreasing and reaches its nominal level.

Due to its excellent design quality, V480LC80CPX10 is suitable for use in various automobile, industrial, consumer and medical applications. The varistor can be used for ESD, EFT, surge and lightning protection against over-voltage conditions present in automotive, industrial, consumer and medical applications. In addition, it is able to reduce the risk of fire and system damage on account of its excellent Noise Reduction Effect (NRF) and High Surge ThroughCapability (HSTC) features. As the varistor can provide reliable protection against destructive high voltage pulses with simple installation, it is easily preferred by most automotive, industrial, consumer and medical applications.

Apart from providing excellent surge protection capabilities, V480LC80CPX10 also offers cost-effective response, small form factor and relatively low inductance. The low inductance capability of this varistor prevents many potential issues such as ringing, ground bounce, and crosstalk. This varistor also does not require a heatsink and can be easily replaced using the same mounting method.

The V480LC80CPX10 is a thermally stable and highly reliable surge protection device suitable for many applications. Its strong protectional capabilities, cost-effectiveness and low inductance makes it a preferred choice for many automotive, industrial, consumer and medical applications.
