V301HA40

TVS - Varistors, MOVs

V301HA40 is one type of surge protection device, mainly used in micro-computer power supply, line filter and various power supply protection, power supply of external circuit etc. It has a wide application range and high protection performance.

Applications of V301HA40

The V301HA40 can be used in a variety of application fields. It is mainly used in high-frequency current surge suppression, low voltage lightning protection, line transmission system, power supplies, automotive conversion switches, power modules, inverters, converters and other electrical appliances.

It is also suitable for protecting microcomputer power supply, line filter and various power supply protection, power supply of external circuit, audio, video equipment and other equipment. In addition, it can be used in the protection of sensitive electronic products such as cameras, recorders, monitors, etc. to improve the safety of products.

Working Principle of V301HA40

The V301HA40 is composed of a ceramic body, semiconductor dielectrics and two metal electrodes, and the control chip inside is responsible for controlling the switching of the semiconductor dielectric material. When the working voltage is up to a certain level, the semiconductor dielectric material will activate immediately and insulate the inner control chip, thus achieving the purpose of suppression surge current.

When the electrical storm charges a dangerous level, the bond overvoltage will be triggered, and the two electrodes of the V301HA40 will also be glowing. Its field effect causes the outer protective layer will produce dielectric insulation layer which can effectively protect people and equipment from electric shock risks.

Under normal circumstances, the control chip in the V301HA40 will maintain a low impedance, so that the normal current is not significantly affected. When the normal current is too large, causing the leakage current to exceed the reference value, the internal control chip will open instantaneously and cause the inner protection device to break, thereby realizing the current protection of the appliance.

Conclusion

V301HA40 has very wide application fields, high protection effect and many advantages. In the correct disassembling and wiring, can play the protective effects in the protection of people and equipment from electric shock or power leakage, providing a strong guarantee for the safety of life and property.
