Available on
commercial
versions
1 Watt Surface Mount
Zener Diodes
Qualified per MIL-PRF-19500/115
DESCRIPTION
Qualified Levels:
JAN, JANTX, and
JANTXV
This surface mountable Zener diode series is similar to the 1N3016B-1 through 1N3045B-1
JEDEC registration in the DO-13 package except that it meets the surface mount DO-213AB
outline. It is an ideal selection for applications of high density and low parasitic requirements.
Due to its glass hermetic seal qualities and metallurgically enhanced internal construction, it is
also well suited for high-reliability applications where it is available in JAN, JANTX, and
JANTXV military qualifications. Lower voltages are also available in the 1N3821AUR-1
through 1N3828AUR-1 series (3.3 V to 7.5 V) in the same package (see separate data sheet).

*JEDEC Registered Data.
NOTES:
1.
2.
†Not JEDEC Data.
Zener voltage (
V
Z
) is measured with junction in thermal equilibrium with still air at a temperature of 25
o
C. The test currents (I
ZT
) at
nominal voltages provide a constant 0.25 watts.
The Zener impedance is derived when a 60 cycle ac current having an rms value equal to 10% of the dc Zener current (I
ZT
or
I
ZK
) is superimposed on I
ZT
or I
ZK
. Zener impedance is measured at 2 points to ensure a sharp knee on the breakdown curve
and to eliminate unstable units. See
MicroNote 202
for variation in dynamic impedance with different Zener currents.
These values of I
ZM
may often be exceeded in the case of individual diodes. The values shown are calculated for a unit at the high
voltage end of its tolerance range. Allowance has also been made for the rise in Zener voltage above V
ZT
that results from Zener
impedance and the increase in junction temperature as a unit approaches thermal equilibrium at a dissipation of 1 watt. The I
ZM
values shown for +/- 5% tolerance units may be used with little error for +/- 10% tolerance units, but should be reduced by 7% to
include a +/- 20% tolerance unit near the high voltage end of its tolerance range.
