Bourns GMOV™ overvoltage protection components

Bourns is introducing the company’s innovative GMOV™ line of hybrid overvoltage protection components combining the patented, space-saving FLAT™ Gas Discharge Tube (GDT) technology with a Metal Oxide Varistor (MOV) to create a compact and enhanced overvoltage protector that is a drop-in replacement for standard 14 and 20 mm MOVs.

Bourns designed its new GMOV™ family to be an enhanced protection solution that helps overcome degradation and catastrophic failure issues that can occur in discrete MOVs that are subjected to transient surges or temporary overvoltage exceeding their maximum rated values. The GDT is used to isolate the MOV from the line voltage so it remains “on call but not on duty,” thereby shielding it from transients and temporary overvoltage spikes that typically damage the MOV over time. Another significant benefit of combining the two technologies is that the GMOV™ device offers ultra-low leakage (<0.1 µA) helping to reduce damage due to watt loss heating. The result is a higher reliability protection
solution with virtually zero standby energy consumption.

GMOV™ products are currently offered in 14 and 20 mm versions with RMS ratings ranging from 45 Vrms to 320 Vrms. The 14 mm version has a maximum surge current rating of 6 kA on an 8/20 µs current waveform, while the 20 mm version tops out at a robust 10 kA.
