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-7 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-7
(DO-204AA)
