Press Release: Development of New Products for Lightning Protection Components for xEV and AI Server Power Supplies - Surge Absorber Achieving High-Speed Response and Surge Capacity of 5,000A

Mitsubishi Materials Corporation has developed the high-performance lightning protection component (surge absorber) "DH53" series, which features fast response and high surge tolerance, to address abnormal voltage (surge) measures for electronic devices that require high safety and stable operation, such as xEVs and power supplies for rapidly developing AI servers.
Until now, our company has supplied surge absorbers for surge protection in xEVs (chargers and onboard OBCs) and various power supplies, receiving high praise. Recently, due to the progression of global warming leading to more extreme weather, including an increase in thunderstorm days, the risk of electronic devices being exposed to unexpected surges has risen. As a result, there is a growing demand for surge absorbers with even higher responsiveness and surge tolerance for electronic devices that require high safety and stable operation.
We have successfully developed the "DH53" series of surge absorbers, which improves the surge tolerance from the conventional 3,000A to 5,000A while maintaining a high surge lifespan and fast response. This will contribute to enhancing the design flexibility and stable operation of electronic devices such as charging equipment for xEVs and power supplies for AI servers, which are increasingly demanding higher performance.
