HIGH-SPEED TRANSIENT SURGE PROTECTORS
UNI-IMPS
DESCRIPTION
CP Clare’s UNI-IMP high-speed transient surge protectors (0.55-20kV) provide the ultimate protection from high-
energy, fast-rising transients such as Nuclear EMP. These devices are 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 these devices allows for direct placement on high-
frequency lines and antenna feeds without excessive loading.
