ORDERING INFORMATION
CG3’s with other breakdown voltages in the 1.0-8.5kV range are
available upon request. A complete part number is represented by
the digits below. For example, CG3-1.5 is a non-leaded 1500V
device, CG3-5.0L is a leaded 5000V device, and CG3-7.5LTR is a
leaded 7500V device on tape-and-reel per EIA standard RS-296-D.
