The B72207S1140K111 is a Varistor manufactured by EPCOS, which belongs to the TVS - Varistors, MOVs category. The B72207S1140K111 has a variety of applications and a unique working principle.

In general, varistors are used in a variety of applications for voltage protection from surges and overvoltages. This device is no different - its purpose is to provide effective overvoltage protection from transients, without adding clutter or complexity to the circuit board. The device is able to provide protection against both AC and DC transients, by dissipating or reflecting the surge or spike current. In this way, the voltage seen by the other components in the system is kept in safe levels.

The B72207S1140K111 is a perfect match for lightning protection and motor control applications. It is able to dissipate high peak surge currents of up to 70A (8/20us wave shape). It is also highly effective at providing protection against indirect lightning strokes. The device has a clamping voltage of a maximum of 115V, making it suitable for low voltage systems.

The B72207S1140K111 also features a slim design, with an ultra-compact case size. This allows for easier placement and assembly. This also helps to improve system efficiency, as the device does not obstruct air flow or interfere with other components.

The working principle of this device is quite simple. When a surge or spike occurs, the stored electric charge is rapidly moved through the device. This process creates an electrical field between the two electrodes. This electric field is able to dissipate or reflect the surge. The device is able to clamp the voltage to its breakdown voltage, ensuring it does not exceed safe levels.

The B72207S1140K111 is a perfect choice for a variety of overvoltage protection applications. It can provide effective protection from both AC and DC transients, while still featuring a slim design and low clamping voltage. This makes it ideal for low voltage applications. The device also features an ultra-compact case size, making it easy to place and assemble.
