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.
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.
