DESCRIPTION  
APPEARANCE  
This surface mountable 1 watt Zener diode series is electrically equivalent to  
the 1N4728A thru 1N4764A registration in the DO-41 equivalent package  
except that it meets the JEDEC surface mount outline DO-213AB. It is an  
ideal selection for applications of high density and low parasitic requirements  
for voltage regulation. Standard voltage tolerance is +/- 5% with tighter  
tolerances available down to 1%. With its glass hermetic qualities, it may  
also be used for high reliability applications when required by a source  
control drawing (SCD).  
DO-213AB  
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
