Gas Discharge Tube Arresters (GDT) are overvoltage protectors designed to absorb or redirect electric surges without causing a short circuit. GDTs are also used to reduce the effects of lightning strikes, something that many power grids and communication systems rely on for protection against voltage and power surges. The PMT835006F is a type of GDT marketed by the Panasonic Corporation. This article provides a brief overview of the application fields and working principle of the PMT835006F.

Application Field

The PMT835006F is most commonly used in the telecommunications industry. This device provides overvoltage protection for telecommunication lines and cables, including LAN/WAN, CATV and Free-space optical communication lines. It is also used in RF circuits, such as electronic switching systems, where it can reduce power surges from lightning, electrostatic discharge, and other powerful energy forms. Finally, the PMT835006F is effective in protecting components in equipment related to power generation, transmission, and distribution.

Working Principle

The PMT835006F incorporates a metal oxide varistor (MOV) and a gas discharge tube (GDT). When an overvoltage occurs, the MOV begins to clamp down on the surge voltage to protect the device and the connected cables or components. The MOV is also designed to automatically reset after the voltage falls to a normal range. The GDT part of the device begins to operate when the MOV is unable to absorb the excess electrical energy. This process will trigger a spark-like discharge that safely reroutes the energy away from the cables and components. As part of its protection, the PMT835006F provides shielding from both overvoltage and transient noise surge.

Conclusion

The PMT835006F is a type of GDT designed by Panasonic to provide protection from power and voltage surges. This device incorporates a MOV and GDT to absorb and redirect an overvoltage safely. It is most commonly used in telecommunications systems, along with RF circuits and power generation, transmission, and distribution equipment. By understanding the application field and working principle of the PMT835006F, users can ensure that their system is properly protected from voltage shock and power surges.
