GMOV™ Hybrid Overvoltage Protector Overview
By combining two technologies, the Bourns® GMOV™
component eectively elminates leakage and most
damage due to watt loss heating, resulting in a protection
solution with zero standby energy consumption. The eect
of no leakage signicantly increases the MTBF (Mean Time
Between Failures) for the MOV.
Damage due to temporary overvoltage is mitigated
by selecting a GMOV™ component with a Maximum
Continuous Operating Voltage rating (MCOV) higher than
any expected voltage swells. In this case, the GDT isolates
the MOV from the circuit until such time that the voltage
exceeds the turn-on voltage of the GDT. This isolation
reduces the likelihood that the MOV will be damaged and
prematurely fail.
The GMOV™ component also protects against conditions
that cause some designs to use a thermally protected
MOV (TMOV). The function of the thermal protection is
to provide a fail open condition that would remove the
component from the circuit and allow for a safe failure of
the component under a thermal runaway condition.
The GMOV™ component is a long life, reliable protection
solution that provides a higher level of performance and
safety compared to standard MOVs. The Bourns® GMOV™
components are ideal in AC applications where conditions
are less than predictable or uncontrolled.
