DESCRIPTION
APPEARANCE
The popular 1N5221 thru 1N5281B 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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
