SMOV34S271NP

SMOV34S271NP is a component belonging to the TVs - Varistors, MOVs family. As such, it is mainly used for protection purposes. It will ensure transient protection that will absorb and repel any surge within its circuitry. It is often used in audio and video applications such as high resolution displays, professional production tools, or even high-end home theater systems.

This component is specifically engineered to handle electrostatic discharge issues. It combines unidirectional and bidirectional protection capabilities, allowing it to act as a compact surge protector for audio and video equipment. This product was designed to provide excellent performance, while remaining cost-effective.

In terms of its working principle, the SMOV34S271NP is a so-called overvoltage protection device. In overvoltage protection devices, the trigger voltage is normally determined by the voltage present in the application. When the voltage reaches the trigger voltage, the protection device begins to conduct current allowing an overload to be diverted from circuit components to the earth.

This component uses a highly resistant matrix combined with zinc oxide (ZnO). This material is subjected to a very specific process, where it is coated with multiple layers of different materials to provide maximum protection. When exposed to a voltage higher than the trigger voltage, the zinc oxide acts as a semiconductor and conducts current from the protected component. This allows an overload to be diverted from the protected component to the earth.

The output current of the device is proportional to the rate of increase of the voltage. This is known as clamping voltage and is an indication of the device\'s safety level. This device has a clamping voltage of 34V and is therefore suitable for use in audio, video, and computer applications where protection from surges is necessary.

In conclusion, the SMOV34S271NP is a very useful component that provides effective protection from transients for audio, video, and computer applications. It combines a highly resistant matrix with zinc oxide to provide superior protection from transient voltages, while the clamping voltage is an indication of the safety level of the component.
