DESCRIPTION
APPEARANCE
This well established zener diode series for the 1N3016 thru 1N3051
JEDEC registration in the metal case DO-13 package provides a glass
hermetic seal for 6.8 to 200 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 thru
1N3830 series (3.3 V to 7.5 V) in the same package (see separate data
sheet). Microsemi also offers numerous other Zener diode products for a
variety of other packages including surface mount.

*JEDEC Registered Data. Not JEDEC Data.
NOTES: 1. When using JEDEC numbers, B suffix signifies +/-5% tolerance on nominal zener voltage. The suffix A is used to identify +/-10%
tolerance; no suffix indicates +/-20% tolerance: suffix C is used to identify +/- 2%; and suffix D is used to identify +/- 1% tolerance.
2.
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.
3.
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.
4.
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.
