Bourns IsoMOV protectors

The IsoMOV protectors from Bourns enable product designers to tailor or upgrade surge protection without the need for large, low-performing alternatives.

The hybrid protection component integrates the GDT function directly into the MOV itself, providing a high level of surge protection performance and operational life. Combining both devices into a single package allows the GDT to block leakage currents through the MOV that may lead to premature failure, making the MOV inherently more robust without adding additional components into the circuit design.

The protectors enable designers to tailor the surge protection performance to their space requirements and to upgrade their MOV overvoltage protection to include the benefit of GDT isolation without a PCB redesign. Industry-standard pin layouts are said to offer a performance upgrade over same-size standard MOVs in a pin-to-pin drop-in-replacement form factor.

Applications include electric vehicle charging systems, industrial power supplies, powerline communications and high-speed information and communication technology (ICT) equipment, as well as a wide range of certain harsh environment or remote, exposed applications where repairs can be both physically challenging and expensive to perform.
