DESCRIPTION  
APPEARANCE  
The 1N5221BUR thru 1N5281BUR series of 0.5 watt Zener Voltage  
Regulators provides a surface mount equivalent to the popular JEDEC  
registered 1N5221B to 1N5281B for 2.4 to 200 volts in standard 5%  
tolerances as well as tighter tolerances identified by different suffix letters on  
the part number. These are also available with an internal-metallurgical-  
bond option by adding a “-1” suffix (see separate data sheet). Microsemi  
also offers numerous other Zener products to meet higher and lower power  
applications.  
DO-213AA  
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
