1N5985UR thru 1N6031BUR
( or MLL5985 thru MLL6031B)
Surface Mount 500 mW Zener Diodes
SCOTTSDALE DIVISION
DESCRIPTION
The popular 1N5985UR thru 1N6031BUR (or MLL5985 thru MLL6031B) 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 with an internal metallurgical bond option by adding a “-1” suffix
(see separate data sheet) including various equivalent military screening levels 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 without a suffix letter before “UR” indicates a 20% tolerance. For 10%
tolerance, add suffix A; for 5% tolerance, add suffix B (as shown); for 2% tolerance add suffix C; for 1% tolerance, add suffix D.
** These may also be ordered as MLL5985B thru MLL6031B for the applicable part number and tolerance in this series.
NOTES:

3.
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 (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
case current for any tolerance device:
P
I
ZM
= V
ZM
Where V
ZM
is the high end of the voltage tolerance specified and P is the rated power of the device.
