DESCRIPTION APPEARANCE
The popular 1N5985UR-1 thru 1N6031BUR-1 (or MLL5985-1 thru MLL6031B-1)
series of 0.5 watt Zener Voltage Regulators provides 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-surface-mount DO-
213AA 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-213AA
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES APPLICATIONS / BENEFITS

to 1N6031
• Similar to operating current conditions of the BZV55
Pro Electron series of Zener products in Europe
• Internal metallurgical bonds
• 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.
• Axial-leaded equivalents available as 1N5985 to
1N6031 in the DO-35 package including “-1” suffix
options (consult factory for others)
• 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
• Nonsensitive to ESD (MIL-STD-750 Method 1020)
• Minimal capacitance (see Figure 2)
• Inherently radiation hard as described in Microsemi
MicroNote 050
MAXIMUM RATINGS MECHANICAL AND PACKAGING

* Indicates JEDEC Registered Data. The type number without a suffix letter before the “UR” suffix indicates a +/-20% tolerance.
For 10% tolerance, add suffix A; for 5% tolerance, add suffix B (as shown); for 2% tolerance suffix C; for 1% tolerance suffix D.
** These part numbers may also be ordered as MLL5985B-1 thru MLL6031B-1 for the applicable part number and tolerance in
this series.
NOTES:
1. Zener Impedance is derived from the 1 kHz ac voltage that results when an ac current having an rms value equal to 10% of dc
zener current (IZT or IZK) is superimposed on IZT or IZK. 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 IZM shown is for the nominal voltages. The following formula can be used to determine the worst
case current for any tolerance device:
IZM =
Where VZM is the high end of the voltage tolerance specified and P is the rated power of the device.
