V18AUMLA1812A

The V18AUMLA1812A is a part of the TVS - Varistors, MOVs family, designed for the purpose of clamping and diverting voltage transient events. It is a non-polar device that works by providing electrical protection to exposed circuit components in applications with mishandled loads or large power surge events. Its working principle is based on the varistor mechanism, where a large voltage event generates a potential barrier that prevents further current distortion and/or damage.

The V18AUMLA1812A is designed to provide near instantaneous response times (50ns) to large transient voltage events. It can be used to clamp voltage up to the rated V18AUMLA1812A maximum working voltage (85V), while still allowing normal circuit operation within its normal operating voltage range (24V to 85V).

The V18AUMLA1812A is used for electrical appliance protection such as computers, TVs, game consoles, and other sensitive electronic devices. It is used for both industrial and consumer applications, to protect against large power surges, voltage transients, and sudden overloads. In addition, it is also used in some home appliances such as washing machines and refrigerators as well as power cords to help prevent sudden power surge damage to these components.

The V18AUMLA1812A is also useful in many other applications such as Automotive, Telecom, Security, Broadcasting, Energy Management, LED Drivers, and Lighting Control. It can be used in any system or device where transient voltage or power surges are common, including ATMs, medical equipment, data communications, fire alarms, power supplies and various other electrical applications.

The varistor mechanism of the V18AUMLA1812A works by clamping the bursts of voltage, and diverting it away from the primary component or circuit. This mechanism works by using a metal-oxide varistor which has a voltage dependent resistance across its terminals, allowing it to conduct current when the voltage exceeds its rated clamping voltage. This then prevents further current distortion and/or damage to the components, as well as preventing the failure of the entire system.

In addition, the V18AUMLA1812A is designed to be a self-resettable device, so it can be used in applications that require repetitive voltage transient events without the need to replace the device. This makes it an ideal component for industrial and consumer applications where repeated exposure to transient voltage events is expected, without compromising its electrical performance.

Overall, the V18AUMLA1812A is a very versatile and reliable device for providing electrical protection against large transient voltage events and current distortion. Its varistor mechanism allows for near instantaneous response times and its self-resettable design makes it suitable for both industrial and consumer applications. This makes it an essential component for a variety of systems and applications, where protection against transient voltage events is critical.
