DESCRIPTION
This well established Zener diode series for the 1N3016B-1 through 1N3045B-1 JEDEC
registration in the glass DO-41 package provides a glass hermetic seal for 6.8 to 110 volts. 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 1N3821 through

*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.
