1N4728AP thru 1N4764AP (PLASTIC)
Silicon 1 Watt Zener Diodes
DESCRIPTION
The popular 1N4728A thru 1N4764A series of 1.0 watt Zeners provides
voltage regulation in a selection from 3.3 to 100 volts in 5% tolerances with
other tolerances also available as identified by different suffix letters on the
part number. These plastic encapsulated Zeners are moisture classified as
Level 1 with no dry pack required and are also available in various military
screening levels by adding a prefix identifier as also described in the
Features section. Microsemi also offers numerous other Zener products to
www.DataSheet4Um.coemet higher and lower power applications.
