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.

Devices in the PMT/UMT(275) series with other breakdown voltages
in the 350-2500V range are available upon request.
A complete part number is represented by the digits below. Break-
down voltages are expressed in Volts for devices <1000V and kV for
devices
1kV. For example, PMT(275)350 is a 350V PMT(275) series
device, and UMT(275)2.0 is a 2kV UMT(275) series device.
