DESCRIPTION
The 1N5913BG-5956BG series of 1.5 watt Zeners provides voltage regulation in a selection
from 3.3 to 200 volts with a variety of tolerances available. They are also available in various
military equivalent screening levels for high reliability. These glass encapsulated Zeners with
a G suffix provide hermetic-sealed qualities and higher rated temperature beyond that
optionally provided in equivalent plastic-body constructions (P suffix) for the same JEDEC part
numbers. Both package options are available from Microsemi.
