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.
