1N4728AP thru 1N4764AP,e3 (PLASTIC)  
Silicon 1 Watt Zener Diodes

DESCRIPTION  
APPEARANCE  
The popular 1N4728AP thru 1N4764AP series of 1.0 watt Zeners provides  
voltage regulation in a selection from 3.3 to 100 volts in 5% tolerances with  
other tighter tolerances also available as identified by different suffix letters  
in the part number. These plastic encapsulated Zeners are moisture  
classified as Level 1 with no dry pack required. They are also available in  
various military screening levels by adding a prefix identifier as described in  
the Features below. These plastic molded Zeners with a P suffix provide a  
lower thermal resistance compared to the glass-body (G suffix) option for  
these same JEDEC part numbers. Both package options are available by  
Microsemi in RoHS Compliant devices with an “e3” suffix. Microsemi also  
offers numerous other Zener products to meet higher and lower power and  
test current applications.  
DO-41 or  
DO-204AL  
(Plastic)
