Leveraging Advanced Protection in Next-Gen Power Systems

Oct. 13, 2021
Using the latest passives such as Bourn’s IsoMOV hybrid protection components can improve power circuit performance and operational life, while providing enhanced device reliability.

With all of the attention being paid to high-profile power advancements like smart-device topologies and wide-bandgap semiconductors, it is easy to overlook what’s going on with novel power components. Recently Bourns introduced its IsoMOV protector, presented as one of the most significant breakthroughs in MOV (metal oxide varistor) device designs in the last few decades.

To get a handle on what the device can mean to the electronic design community, we spoke with Lee Bourns, Marketing Director for Circuit Protection, and Kelly Casey, Engineering Director, about the IsoMOV family of protection devices. Here is the presentation they gave us:

Integrating a Gas Discharge Tube (GDT) function directly into the MOV itself, the solution provides elevated levels of surge protection, ensuring performance, operational life, and enhanced device reliability. Offering performance specifications usually found in larger traditional MOV devices, Bourns IsoMOV protectors can better tailor surge protection performance to space requirements, upgrading MOV overvoltage protection to include GDT isolation without a PCB redesign.

Targeting industrial, power line communications, high-speed information and communication technology (ICT) equipment, the 125°C-rated IsoMOV protector also offers low leakage and is well-suited for a wide range of harsh environment or remote, exposed applications where repairs can be both physically challenging and expensive to perform. The Bourns IsoMOV protector series is UL 1449 Type 5 recognized and available now.
