The solid-state protection devices known as Varistors, MOVs (metal oxide varistors) and TVS (transient voltage surge suppressors) are all used in different applications for protecting against voltage transients. These devices have become integral components of any power, data, or communication system. The purpose of this article is to explain the application field and working principle of 82536040, one type of variety of MOVs, and outline the salient features of the device.

A 82536040 surge protectors is designed to protect against transients on the AC power line or other high-frequency signals such as RS-232 signals. It works by clamping the voltage when it exceeds a certain preset level. When the incoming voltage exceeds the clamping voltage of the MOV, the MOV will begin to conduct current, which effectively reduces the clamping voltage. This ensures that the MOV maintains the desired clamping voltage, even if the incoming voltage increases.

The 82536040 is suitable for a wide range of applications including industrial control systems, electrical and building automation, home security, appliance, communication (data, telephone, and satellite) and automotive applications. Additionally, the device can be used in medical equipment and measurement/instrumentation applications as well.

The 82536040 is designed to provide high peak current handling capacity. It has a hold current rating of 72A and can withstand surge impulses of up to 2000V and 200A. It also has a fast response time, and its fast reacting, bidirectionally symmetric response ensures that surge protection is provided against both polarity voltage transients.

In terms of its features, the 82536040 is UL1449 listed, ENEC and RoHS compliant, and is designed for mounting on printed circuit boards. It is supplied in an epoxy package which provides protection against moisture, dust and other contaminants that could reduce the device\'s ability to provide surge protection. Additionally, the device is designed with a safety feature, which ensures that it will not be damaged by short-duration over-voltages.

The working principle of the 82536040 is quite simple. When an over-voltage occurs on the AC line, the device will begin to conduct current until the voltage is brought down to the preset level. Once this is achieved, the device will stop conducting current and the overvoltage will be suppressed. The device features a low thermal impedance, allowing it to dissipate heat quickly and effectively.

The 82536040 surge protector is widely used in applications where over-voltages must be controlled and prevented from causing damage to components. It is well-suited to providing protection against lightning, power surges, and electro-magnetic interference (EMI). The device is both reliable and cost-effective, making it a popular choice of engineers in the field. It is also very easy to install in any system, requiring only basic skills and tools.

In summary, the 82536040 is an exceptionally high-performance, reliable surge protection device. It is suitable for a wide range of applications, and features a high peak current handling capacity, fast response time, and bidirectional symmetric protection. Furthermore, the device is UL1449 listed, ENEC and RoHS compliant, and is easy to install in any system. All of these features make the 82536040 an excellent choice for protecting against overvoltage transients.
