DESCRIPTION
STANDARD VOLTAGES
APPLICATIONS
FEATURES
CP Clare’s PMT(275) and UMT(275) Series surge protectors (350-500V and 550-2500V respectively) provide a
high level of protection from high-speed, high-current transient surges. These devices are constructed using a
proprietary semiconductor junction process which results in nanosecond response times combined with peak
current ratings in excess of 20kA.
