SILICON 2.0 Watt ZENER DIODES

DESCRIPTION  
APPEARANCE  
The SMBJ4728A-4764A and SMBG4728A-4764A series of surface mount  
2.0 watt Zeners provides voltage regulation in a selection from 3.3 to 100  
volts with different tolerances as identified by suffix letter on the part  
number. This surface mount product series with lower thermal resistance  
features is equivalent to the JEDEC registered 1N4728 thru 1N4764A  
with identical electrical characteristics except it is rated at 2.0 W instead  
of 1.0 W. It is available in J-bend design (SMBJ) with the DO-214AA  
package for greater PC board mounting density or in Gull-wing design  
(SMBG) in the DO-215AA for visible solder connections. Microsemi also  
offers numerous other Zener products to meet higher and lower power  
applications.  
NOTE: All SMB series are equivalent  
to prior SMS package identifications.  
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
