1N4728AG thru 1N4764AG, e3 (Glass)

Silicon 1 Watt Zener Diodes

S C O T T S D A L E D I V I S I O N

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)
