1N5985 thru 1N6031-1, e3 DO-35

Axial-Leaded 500 mW Zener Diodes

SCOTTSDALE DIVISION

DESCRIPTION

The popular 1N5985 thru 1N6031 series of 0.5 watt Zener Voltage Regulators

provides a 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 axial-leaded DO-35 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.
