DESCRIPTION
APPEARANCE
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
DO-213AA
products to meet higher and lower power applications.
