1N5985 thru 1N6031-1, e3 DO-35
Axial-Leaded 500 mW Zener Diodes
SCOTTSDALE DIVISION
DESCRIPTION
The popular 1N5985 thru 1N6031 series of 0.5 watt Zener Voltage Regulators
provides a selection from 2.4 to 200 volts in standard 5% or 10% tolerances as
well as tighter tolerances identified by different suffix letters on the part number.
These glass axial-leaded DO-35 Zeners are also available in various military
screening levels by adding a prefix identifier as described in the Features
section. Microsemi also offers numerous other Zener products to meet higher
and lower power applications.

*Indicates JEDEC Registered Data. The type number listed indicates a 20% tolerance. For 10% tolerance, add
suffix A; for 5% tolerance, add suffix B; for 2% tolerance add suffix C; for 1% tolerance, add suffix D.
NOTES:
1.
Zener Impedance is derived from the 1 kHz ac voltage which results when an ac current having an rms value equal to 10% of
dc zener current (I
ZT
or I
ZK
) is superimposed on I
ZT
or I
ZK
. See MicroNote 202 for dynamic impedance variation with other
operating currents.
Voltage Measurements to be performed 20 seconds after application of the dc test current.
The maximum zener current I
ZM
shown is for the nominal voltages. The following formula can be used to determine the worst
P
case current for any tolerance device:
V
ZM
I
ZM
=
Where V
ZM
is the high end of the voltage tolerance specified and P is the rated power of the device.
