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
