Bourns® breakthrough GMOV™ component combines a Metal Oxide Varistor (MOV) and a Gas Discharge Tube (GDT) with their patented space-saving FLAT® technology. This new hybrid product provides a compact form factor that is a drop-in replacement for a standard 14mm or 20mm disc size MOV.
The GMOV™ component is designed to be an enhanced protection solution that minimizes degradation and catastrophic failure issues that can occur with discrete MOVs when they are subjected to transient surges and temporary overvoltage conditions exceeding maximum rated values.
Equivalent Circuit
The “on-call but not on-duty" isolation of the MOV from line voltage by the GDT effectively shields the MOV from transients and temporary overvoltage spikes that typically damage the MOV over time. This is achieved effectively in the GMOV™ component where the GDT isolates the MOV from the circuit until such time as the voltage exceeds the turn-on voltage of the GDT.
The integrated GDT isolates the MOV from line voltage and smaller transients, which over time would damage the MOV resulting in premature failure. Current leakage from the device is also eliminated by the series GDT and mitigates damage of the MOV due to watt loss heating.
GMOV™ Construction
Whilst Disc MOVs remain a popular solution for AC and DC protection, currently designers need to use extra discrete components for additional protection against unstable electrical service. In many cases, the discrete component solutions are not tested and proven to work together like the GMOV™ component.
