1N5913BG – 1N5956BG
Available Axial-Leaded 1.5 Watt Glass Zener Diodes
Screening in
reference to
MIL-PRF-19500
available
DESCRIPTION
The 1N5913BG-5956BG series of 1.5 watt Zeners provides voltage regulation in a selection
from 3.3 to 200 volts with a var iety 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.

NOTES:
1. Zener voltage (VZ) is measured at TL = 30 oC and 90 seconds after application of dc current.
2. The Zener im pedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10% of the
dc Zener current (IZT or IZK) is superimposed on IZT or IZK. See MicroNote 202 for Zener impedance variation with di ff erent operating
currents.
