SURFACE MOUNT 500 mW Zener Diodes
DESCRIPTION
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.

* 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:

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:
I
ZM
=
P
V
ZM
Where V
ZM
is the high end of the voltage tolerance specified and P is the rated power of the device.
