DESCRIPTION
APPEARANCE
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.
DO-35
(DO-204AH
)
IMPORTANT: For the most current data, consult MICROSEMI's website:

FEATURES
APPLICATIONS / BENEFITS
JEDEC registered 1N5985 to 1N6031
Similar to operating current conditions of the BZX55
Pro Electron series of Zener products in Europe
Internal bonds optionally available with "-1" suffix
Options for screening in accordance with MIL-PRF-
19500 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers with "-1" suffix.
Surface mount equivalents available as MLL5985 to
MLL6031 in the DO-213AA MELF style package
including "-1" suffix options (consult factory for others)
DO-7 glass body axial-leaded Zener equivalents are
also available
Regulates voltage over a broad operating current
and temperature range
Extensive selection from 2.4 to 200 V
Standard voltage tolerances are plus/minus 5% with
B suffix, 10 % with A suffix identification
Tight tolerances available in plus or minus 2% or
1% with C or D suffix respectively
Flexible axial-lead mounting terminals
Nonsensitive to ESD (MIL-STD-750 Method 1020)

*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.
2.
Voltage Measurements to be performed 20 seconds after application of the dc test current.
3.
The maximum zener current I
ZM
shown is for the nominal voltages. The following formula can be used to determine the worst
case current for any tolerance device:
P
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.
