Product Summary

The UNI3405 is a high-speed transient surge protector. The UNI3405 provides the ultimate protection from high-energy, fast-rising transients such as Nuclear EMP. The UNI3405 is constructed using a proprietary semiconductor junction process that results in nanosecond response times combined with peak current ratings in excess of 20kA. A unique benefit of this technology is that the breakdown voltage is virtually independent of the rise time of the transient. In addition, the low capacitance of the UNI3405 allows for direct placement on high-frequency lines and antenna feeds without excessive loading. The applications of the UNI3405 include Antenna feedlines, Test equipment, Video displays, Medical electronics, Instrumentation circuits.
