Description

General part information

1N5989UR-1-Zener-Diode Series

The popular 1N5985B-1 thru 1N6031B-1 series of 0.5 watt Zener voltage regulators provides a selection from 2.4 to 200 volts in 10%, 5%, 2% and 1% tolerances. These axial-leaded, glass, DO-35 packaged Zeners are also available in various military equivalent screening levels by adding a prefix identifier as described in the "part nomenclature" section. Microchip also offers numerous other Zener products to meet higher and lower power applications.
