1N4728AG thru 1N4764AG, e3 (Glass)
1N4728AG-1N4764AG,
e3
DESCRIPTION
APPEARANCE
The popular 1N4728AG thru 1N4764AG glass body 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 on the part number.
These glass encapsulated
Zeners with a G suffix provide hermetic-sealed qualities and higher rated
temperature when required beyond that optionally provided in the same
size DO-41 plastic-body (P suffix) for these JEDEC part numbers. Both of
these package options are available by Microsemi including RoHS
Compliant devices with an “e3” suffix.
A variety of other Zener product
offerings and packages are available by Microsemi to meet higher and
lower power or test current applications.
DO-41 or
DO-204AL
(Glass)
