1N5221 thru 1N5281,e3 DO-7  
500 mW GLASS AXIAL-LEAD  
ZENER DIODES  
S C O T T S D A L E D I V I S I O N  
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)  
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
